sysfs: remove redundant __compat_only_sysfs_link_entry_to_kobj fn
Commit
9255782f7061 ("sysfs: Wrap __compat_only_sysfs_link_entry_to_kobj
function to change the symlink name") made this function a wrapper
around a new non-underscored function, which is a bit odd. The normal
naming convention is the other way around: the underscored function is
the wrappee, and the non-underscored function is the wrapper.
There's only one single user (well, two call-sites in that user) of the
more limited double underscore version of this function, so just remove
the oddly named wrapper entirely and just add the extra NULL argument to
the user.
I considered just doing that in the merge, but that tends to make
history really hard to read.

Pull clk updates from Stephen Boyd:
"There's not much to see in the core framework this time around.
Instead the majority of the diff is the normal collection of driver
additions for new SoCs and non-critical clk data fixes and updates.
The framework must be middle aged.
The two biggest directories in the diffstat show that the Qualcomm and
Unisoc support added a handful of big drivers for new SoCs but that's
not really the whole story because those new drivers tend to add large
numbers of lines of clk data. There's a handful of AT91 clk drivers
added this time around too and a bunch of improvements to drivers like
the i.MX driver. All around lots of updates and fixes in various clk
drivers which is good to see.
The core framework has only one real major change which has been
baking in next for the past couple months. It fixes the framework so
that it stops caching a clk's phase when the phase clk_op returns an
error. Before this change we would consider some negative errno as a
phase and that just doesn't make sense.
Core:
- Don't show clk phase when it is invalid
New Drivers:
- Add support for Unisoc SC9863A clks
- Qualcomm SM8250 RPMh and MSM8976 RPM clks
- Qualcomm SM8250 Global Clock Controller (GCC) support
- Qualcomm SC7180 Modem Clock Controller (MSS CC) support
- EHRPWM's TimeBase clock(TBCLK) for TI AM654 SoCs
- Support PMC clks on at91sam9n12, at91rm9200, sama5d3, and
at91sam9g45 SoCs
Updates:
- GPU GX GDSC support on Qualcomm sc7180
- Fixes and improvements for the Marvell MMP2/MMP3 SoC clk drivers
- A series from Anson to convert i.MX8 clock bindings to json-schema
- Update i.MX pll14xx driver to include new frequency entries for
pll1443x table, and return error for invalid PLL type
- Add missing of_node_put() call for a number of i.MX clock drivers
- Drop flag CLK_IS_CRITICAL from 'A53_CORE' mux clock, as we already
have the flag on its child cpu clock
- Fix a53 cpu clock for i.MX8 drivers to get it source from ARM PLL
via CORE_SEL slice, and source from A53 CCM clk root when we need
to change ARM PLL frequency. Thus, we can support core running
above 1GHz safely
- Update i.MX pfdv2 driver to check zero rate and use determine_rate
for getting the best rate
- Add CLKO2 for imx8mm, SNVS clock for imx8mn, and PXP clock for

Pull tracing updates from Steven Rostedt:
"New tracing features:
- The ring buffer is no longer disabled when reading the trace file.
The trace_pipe file was made to be used for live tracing and
reading as it acted like the normal producer/consumer. As the trace
file would not consume the data, the easy way of handling it was to
just disable writes to the ring buffer.
This came to a surprise to the BPF folks who complained about lost
events due to reading. This is no longer an issue. If someone wants
to keep the old disabling there's a new option "pause-on-trace"
that can be set.
- New set_ftrace_notrace_pid file. PIDs in this file will not be
traced by the function tracer.
Similar to set_ftrace_pid, which makes the function tracer only
trace those tasks with PIDs in the file, the set_ftrace_notrace_pid
does the reverse.
- New set_event_notrace_pid file. PIDs in this file will cause events
not to be traced if triggered by a task with a matching PID.
Similar to the set_event_pid file but will not be traced. Note,
sched_waking and sched_switch events may still be traced if one of
the tasks referenced by those events contains a PID that is allowed
to be traced.
Tracing related features:
- New bootconfig option, that is attached to the initrd file.
If bootconfig is on the command line, then the initrd file is
searched looking for a bootconfig appended at the end.
- New GPU tracepoint infrastructure to help the gfx drivers to get

"More cleanup this cycle, with the final goal of removing the
rtc_time_to_tm and rtc_tm_to_time wrappers. All the drivers that have
been modified for this now are ready for the end of times (whether it
happens in 2033, 2038, 2106, 2127 or even 4052). There is also a
single new driver and the usual fixes and features.
Summary:
Subsystem:
- The rtc_time_to_tm and rtc_tm_to_time wrappers have finally been
removed and only the 64bit version remain.
- hctosys now works with drivers compiled as modules
New driver:
- MediaTek MT2712 SoC based RTC
Drivers:
- set range for 88pm860x, au1xxx, cpcap, da9052, davinci, ds1305,
ds1374, mcp5121, pl030, pl031, pm8xxx, puv3, sa1100, sirfsoc,

- ds1307: DS1388 oscillator failure detection and watchdog support
- jz4740: JZ4760 support
- pcf85063: clock out pin support
- sun6i: external 32k oscillator is now optional, the range is now
handled by the core, providing a solution for 2034"

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO development for the v5.7 kernel cycle.
Core and userspace API:
- The userspace API KFIFOs have been imoproved with locks that do not
block interrupts. This makes us better at getting events to
userspace without blocking or disturbing new events arriving in the
same time. This was reviewed by the KFIFO maintainer Stefani. This
is a generic improvement which paves the road for similar
improvements in other subsystems.
- We provide a new ioctl() for monitoring changes in the line
information, such as when multiple clients are taking lines and
giving them back, possibly reconfiguring them in the process: we
can now monitor that and not get stuck with stale static
information.
- An example tool 'gpio-watch' is provided to showcase this
functionality.
- Timestamps for events are switched to ktime_get_ns() which is
monotonic. We previously had a 'realtime' stamp which could move
forward and *backward* in time, which probably would just cause
silent bugs and weird behaviour. In the long run we see two
relevant timestamps: ktime_get_ns() or the timestamp sometimes
provided by the GPIO hardware itself, if that exists.
- Device Tree overlay support for GPIO hogs. On systems that load
overlays, these overlays can now contain hogs, and will then be
respected.
- Handle pin control interaction with nonexisting pin ranges in the
GPIO library core instead of in the individual drivers.
New drivers:
- New driver for the Mellanox BlueField 2 GPIO controller.
Driver improvements:
- Introduce the BGPIOF_NO_SET_ON_INPUT flag to the generic MMIO GPIO
library and use this flag in the MT7621 driver.
- Texas Instruments OMAP CPU power management improvements, such as
blocking of idle on pending GPIO interrupts"

Revert "dm: always call blk_queue_split() in dm_process_bio()"
This reverts commit
effd58c95f277744f75d6e08819ac859dbcbd351.
blk_queue_split() is causing excessive IO splitting -- because
blk_max_size_offset() depends on 'chunk_sectors' limit being set and
if it isn't (as is the case for DM targets!) it falls back to
splitting on a 'max_sectors' boundary regardless of offset.
"Fix" this by reverting back to _not_ using blk_queue_split() in
dm_process_bio() for normal IO (reads and writes). Long-term fix is

tracing: Do not allocate buffer in trace_find_next_entry() in atomic
When dumping out the trace data in latency format, a check is made to peek
at the next event to compare its timestamp to the current one, and if the
delta is of a greater size, it will add a marker showing so. But to do this,
it needs to save the current event otherwise peeking at the next event will
remove the current event. To save the event, a temp buffer is used, and if
the event is bigger than the temp buffer, the temp buffer is freed and a
bigger buffer is allocated.
This allocation is a problem when called in atomic context. The only way
this gets called via atomic context is via ftrace_dump(). Thus, use a static
buffer of 128 bytes (which covers most events), and if the event is bigger
than that, simply return NULL. The callers of trace_find_next_entry() need
to handle a NULL case, as that's what would happen if the allocation failed.

Python 3.8 changed the output of 'python-config --ldflags' to no longer

This adds a check in the Makefile to determine if PYTHON_CONFIG accepts

Parse event definition strings: FAILED!
This happens because the parser splits names by '-' in order to deal
with cache events. For example 'L1-dcache' is a token in
parse-events.l which is matched to 'L1-dcache-load-miss' by the
following rule:
PE_NAME_CACHE_TYPE '-' PE_NAME_CACHE_OP_RESULT '-' PE_NAME_CACHE_OP_RESULT opt_event_config
And so there is special handling for 2-part PMU names i.e.
PE_PMU_EVENT_PRE '-' PE_PMU_EVENT_SUF sep_dc
but no handling for 3-part names, which are instead added as tokens e.g.
topdown-[a-z-]+
While it would be possible to add a rule for 3-part names, that would
not work if the first parts were also a valid PMU name e.g.
'el-capacity-read' would be matched to 'el-capacity' before the parser
reached the 3rd part.
The parser would need significant change to rationalize all this, so
instead fix for now by adding missing Intel CPU events with 3-part names
to the event parser as tokens.
Missing events were found by using:
grep -r EVENT_ATTR_STR arch/x86/events/intel/core.c

continues syntactically valid but ends up reducing the real size of the
buffer where to format the first line in the screen to 8 bytes, which
makes the formatting at the title at each refresh to produce just the
string "Samples ", duh, fix it by passing the size of the buffer.

perf top: Support hotkey to change sort order
It would be nice if we can use a hotkey in perf top browser to select a
event for sorting.
For example:
perf top --group -e cycles,instructions,cache-misses

perf top: Support --group-sort-idx to change the sort order
'perf report' supports the option --group-sort-idx, which sorts the

For example:
perf record -e cycles,instructions,cache-misses

The perf-report output is sorted by cache-misses.
This patch supports --group-sort-idx in perf-top.

Calloc failed as the symbol__size(sym) is too huge. As show in error
message: start=0x1477100, end=0x80002000, size of symbol is about 2G.
This is the same problem as 'perf annotate: Fix s390 gap between kernel
end and module start (
b9c0a64901d5bd)'. Perf gets symbol information from
/proc/kallsyms in __dso__load_kallsyms. A part of symbol in /proc/kallsyms
from my virtual machine is as follows:
#cat /proc/kallsyms | sort
...
ffff000001475080 d rpfilter_mt_reg [ip6t_rpfilter]
ffff000001475100 d $d [ip6t_rpfilter]
ffff000001475100 d __this_module [ip6t_rpfilter]
ffff000080080000 t _head
ffff000080080000 T _text
ffff000080080040 t pe_header
...
Take line '
ffff000001475100 d __this_module [ip6t_rpfilter]' as example.
The start and end of symbol are both set to
ffff000001475100 in
dso__load_all_kallsyms. Then symbols__fixup_end will set the end of symbol
to next big address to
ffff000001475100 in /proc/kallsyms,
ffff000080080000
in this example. Then sizeof of symbol will be about 2G and cause the
problem.
The start of module in my machine is
ffff000000a62000 t $x [dm_mod]
The start of kernel in my machine is
ffff000080080000 t _head
There is a big gap between end of module and begin of kernel if a samll
amount of memory is used by module. And the last symbol in module will
have a large address range as caotaining the big gap.
Give that the module and kernel text segment sequence may change in
the future, fix this by limiting range of last symbol in module and kernel
to 4K in arch arm64.

Sometimes we may need to override that, for instance, when using

The cgroup sort key is to show cgroup membership of each task.
Currently it shows full path in the cgroupfs (not relative to the root

cgroup in different namespaces will all show same name - "/".
The cgroup sort key should come before cgroup_id otherwise

the given substring.

The file handle (FHANDLE) support is configurable so some systems might not

Had to make the test use the same construct as its later use in

struct {
struct file_handle fh;
uint64_t cgroup_id;
} handle;

struct file_handle fh;

1 error generated.
Deal with this at some point, i.e. investigate if the right thing is to
remove that -Wgnu-variable-sized-type-not-at-end from our CFLAGS, for
now do the test the same way as it is used looks more sensible.

- allow disabling GISA (hardware interrupt injection) and protected
VMs/ultravisor support.
x86:
- New dirty bitmap flag that sets all bits in the bitmap when dirty
page logging is enabled; this is faster because it doesn't require
bulk modification of the page tables.
- Initial work on making nested SVM event injection more similar to
VMX, and less buggy.
- Various cleanups to MMU code (though the big ones and related
optimizations were delayed to 5.8). Instead of using cr3 in
function names which occasionally means eptp, KVM too has
standardized on "pgd".
- A large refactoring of CPUID features, which now use an array that
parallels the core x86_features.
- Some removal of pointer chasing from kvm_x86_ops, which will also
be switched to static calls as soon as they are available.
- New Tigerlake CPUID features.
- More bugfixes, optimizations and cleanups.
Generic:
- selftests: cleanups, new MMU notifier stress test, steal-time test
- CSV output for kvm_stat"

Pull xfs updates from Darrick Wong:
"There's a lot going on this cycle with cleanups in the log code, the
btree code, and the xattr code.
We're tightening of metadata validation and online fsck checking, and
introducing a common btree rebuilding library so that we can refactor
xfs_repair and introduce online repair in a future cycle.
We also fixed a few visible bugs -- most notably there's one in
getdents that we introduced in 5.6; and a fix for hangs when disabling
quotas.
This series has been running fstests & other QA in the background for
over a week and looks good so far.
I anticipate sending a second pull request next week. That batch will
change how xfs interacts with memory reclaim; how the log batches and
throttles log items; how hard writes near ENOSPC will try to squeeze
more space out of the filesystem; and hopefully fix the last of the
umount hangs after a catastrophic failure. That should ease a lot of
problems when running at the limits, but for now I'm leaving that in
for-next for another week to make sure we got all the subtleties
right.
Summary:
- Fix a hard to trigger race between iclog error checking and log
shutdown.
- Strengthen the AGF verifier.
- Ratelimit some of the more spammy error messages.
- Remove the icdinode uid/gid members and just use the ones in the
vfs inode.
- Hold ILOCK across insert/collapse range.
- Clean up the extended attribute interfaces.
- Clean up the attr flags mess.
- Restore PF_MEMALLOC after exiting xfsaild thread to avoid
triggering warnings in the process accounting code.
- Remove the flexibly-sized array from struct xfs_agfl to eliminate
compiler warnings about unaligned pointers and packed structures.
- Various macro and typedef removals.
- Stale metadata buffers if we decide they're corrupt outside of a
verifier.
- Check directory data/block/free block owners.
- Fix a UAF when aborting inactivation of a corrupt xattr fork.
- Teach online scrub to report failed directory and attr name lookups
as a metadata corruption instead of a runtime error.
- Avoid potential buffer overflows in sysfs files by using scnprintf.
- Fix a regression in getdents lookups due to a mistake in pointer
arithmetic.
- Refactor btree cursor private data structures to use anonymous
unions.
- Cleanups in the log unmounting code.
- Fix a potential mishandling of ENOMEM errors on multi-block
directory buffer lookups.
- Fix an incorrect test in the block allocation code.
- Cleanups and name prefix shortening in the scrub code.
- Introduce btree bulk loading code for online repair and scrub.
- Fix a quotaoff log item leak (and hang) when the fs goes down
midway through a quotaoff operation.
- Remove di_version from the incore inode.
- Refactor some of the log shutdown checking code.
- Record the forcing of the log unmount records in the log force
counters.
- Fix a longstanding bug where quotacheck would purge the
administrator's default quota grace interval and warning limits.
- Reduce memory usage when scrubbing directory and xattr trees.
- Don't let fsfreeze race with GETFSMAP or online scrub.
- Handle bio_add_page failures more gracefully in xlog_write_iclog"
