io_uring: optimise locking for local tw with submit_wait
Running local task_work requires taking uring_lock, for submit + wait we
can try to run them right after submit while we still hold the lock and
save one lock/unlokc pair. The optimisation was implemented in the first
local tw patches but got dropped for simplicity.

io_uring: remove redundant memory barrier in io_req_local_work_add
io_cqring_wake() needs a barrier for the waitqueue_active() check.
However, in the case of io_req_local_work_add(), we call llist_add()
first, which implies an atomic. Hence we can replace smb_mb() with
smp_mb__after_atomic().

io_uring/net: handle -EINPROGRESS correct for IORING_OP_CONNECT
We treat EINPROGRESS like EAGAIN, but if we're retrying post getting
EINPROGRESS, then we just need to check the socket for errors and
terminate the request.
This was exposed on a bluetooth connection request which ends up
taking a while and hitting EINPROGRESS, and yields a CQE result of
-EBADFD because we're retrying a connect on a socket that is now
connected.

io_uring/af_unix: defer registered files gc to io_uring release
Instead of putting io_uring's registered files in unix_gc() we want it
to be done by io_uring itself. The trick here is to consider io_uring
registered files for cycle detection but not actually putting them down.
Because io_uring can't register other ring instances, this will remove
all refs to the ring file triggering the ->release path and clean up
with io_ring_ctx_free().

This is beneficial for real world applications that end up issuing
lots of system calls as part of handling work. Normal task_work will
always execute as we transition in and out of the kernel, even for
"unrelated" system calls. It's more efficient to defer the handling
of io_uring's deferred work until the application wants it to be run,
generally in batches.
As part of ongoing work to write an io_uring network backend for
Thrift, this has been shown to greatly improve performance. (Dylan)

already has I_DIRTY_INODE
Performance:
- Always enable i_version counter (as btrfs and xfs already do).
Remove some uneeded i_version bumps to avoid unnecessary nfs cache
invalidations
- Wake up journal waiters in FIFO order, to avoid some journal users
from not getting a journal handle for an unfairly long time
- In ext4_write_begin() allocate any necessary buffer heads before
starting the journal handle
- Don't try to prefetch the block allocation bitmaps for a read-only
file system
Bug Fixes:
- Fix a number of fast commit bugs, including resources leaks and out
of bound references in various error handling paths and/or if the
fast commit log is corrupted
- Avoid stopping the online resize early when expanding a file system
which is less than 16TiB to a size greater than 16TiB
- Fix apparent metadata corruption caused by a race with a metadata
buffer head getting migrated while it was trying to be read
- Mark the lazy initialization thread freezable to prevent suspend
failures
- Other miscellaneous bug fixes
Cleanups:
- Break up the incredibly long ext4_full_super() function by
refactoring to move code into more understandable, smaller
functions
- Remove the deprecated (and ignored) noacl and nouser_attr mount
option
- Factor out some common code in fast commit handling
- Other miscellaneous cleanups"

Pull btrfs updates from David Sterba:
"There's a bunch of performance improvements, most notably the FIEMAP
speedup, the new block group tree to speed up mount on large
filesystems, more io_uring integration, some sysfs exports and the
usual fixes and core updates.
Summary:
Performance:
- outstanding FIEMAP speed improvement
- algorithmic change how extents are enumerated leads to orders of
magnitude speed boost (uncached and cached)
- extent sharing check speedup (2.2x uncached, 3x cached)
- add more cancellation points, allowing to interrupt seeking in
files with large number of extents
- more efficient hole and data seeking (4x uncached, 1.3x cached)
- sample results:
256M, 32K extents: 4s -> 29ms (~150x)
512M, 64K extents: 30s -> 59ms (~550x)
1G, 128K extents: 225s -> 120ms (~1800x)
- improved inode logging, especially for directories (on dbench
workload throughput +25%, max latency -21%)
- improved buffered IO, remove redundant extent state tracking,
lowering memory consumption and avoiding rb tree traversal
- add sysfs tunable to let qgroup temporarily skip exact accounting
when deleting snapshot, leading to a speedup but requiring a rescan
after that, will be used by snapper
- support io_uring and buffered writes, until now it was just for
direct IO, with the no-wait semantics implemented in the buffered
write path it now works and leads to speed improvement in IOPS
(2x), throughput (2.2x), latency (depends, 2x to 150x)
- small performance improvements when dropping and searching for
extent maps as well as when flushing delalloc in COW mode
(throughput +5MB/s)
User visible changes:
- new incompatible feature block-group-tree adding a dedicated tree
for tracking block groups, this allows a much faster load during
mount and avoids seeking unlike when it's scattered in the extent
tree items
- this reduces mount time for many-terabyte sized filesystems
- conversion tool will be provided so existing filesystem can also
be updated in place
- to reduce test matrix and feature combinations requires no-holes
and free-space-tree (mkfs defaults since 5.15)
- improved reporting of super block corruption detected by scrub
- scrub also tries to repair super block and does not wait until next
commit
- discard stats and tunables are exported in sysfs
(/sys/fs/btrfs/FSID/discard)
- qgroup status is exported in sysfs
(/sys/sys/fs/btrfs/FSID/qgroups/)
- verify that super block was not modified when thawing filesystem
Fixes:
- FIEMAP fixes
- fix extent sharing status, does not depend on the cached status
where merged
- flush delalloc so compressed extents are reported correctly
- fix alignment of VMA for memory mapped files on THP
- send: fix failures when processing inodes with no links (orphan
files and directories)
- fix race between quota enable and quota rescan ioctl
- handle more corner cases for read-only compat feature verification
- fix missed extent on fsync after dropping extent maps
Core:
- lockdep annotations to validate various transactions states and
state transitions
- preliminary support for fs-verity in send
- more effective memory use in scrub for subpage where sector is
smaller than page
- block group caching progress logic has been removed, load is now
synchronous
- simplify end IO callbacks and bio handling, use chained bios
instead of own tracking
- add no-wait semantics to several functions (tree search, nocow,
flushing, buffered write
- cleanups and refactoring
MM changes:
- export balance_dirty_pages_ratelimited_flags"

"Most of the changes fall into one of three categories: adding support
for additional devices on existing machines, cleaning up issues found
by the ongoing conversion to machine-readable bindings, and addressing
minor mistakes in the existing DT data.
Across SoC vendors, Qualcomm and Freescale stick out as getting the
most updates, which corresponds to their dominance in the mobile phone
and embedded industrial markets, respectively.
There are 636 non-merge changeset in this branch, which is a little
lower than most times, but more importantly we only add 36 machine
files, which is about half of what we had the past few releases.
Eight new SoCs are added, but all of them are variations of already
supported SoC families, and most of them come with one reference board
design from the SoC vendor:
- Mediatek MT8186 is a Chromebook/Tablet type SoC, similar to the
MT65xx series of phone SoCs, with two Cortex-A76 and six Cortex-A55
cores.
- TI AM62A is another member of the K3 family with Cortex-A53 cores,
this one is targetted at Video/Vision processing for industrial and
automotive applications.
- NXP i.MX8DXL is another chip for this market in the ever-growing
i.MX8 family, this one again with two Cortex-A35 cores.
- Renesas R-Car H3Ne-1.7G (R8A779MB) and R-Car V3H2 (R8A77980A) are
minor updates of R8A77951 and R8A77980, respectively.
- Qualcomm IPQ8064-v2.0, IPQ8062 and IPQ8065 are all variants of the
IPQ8064 chip, with minimally different features.
The AMD Pensando Elba and Apple M1 Ultra SoC support was getting close
this time, but in the end did not make the cut.
The new machines based on existing SoC support are fairly uneventful:
- Sony Xperia 1 IV is a fairly recent phone based on Qualcomm
Snapdragon 8 Gen 1.
- Three Samsung phones based on Snapdragon 410: Galaxy E5, E7 and
Grand Max. These are added for both 32-bit and 64-bit kernels, as
they originally shipped running 32-bit code.
- Two new servers using AST2600 BMCs: AMD DaytonaX and Ampere Mt.
Mitchell
- Three new machines based on Rockchips RK3399 and RK3566: Anberic
RG353P and RG503, Pine64 Pinephone Pro, Open AI Lab
- Multiple NXP i.MX6/i.MX8 based boards: Kontron SL/BL i.MX8MM OSM-S,
i.MX8MM Gateworks GW7904, MSC SM2S-IMX8PLUS SoM and carrier board
- Two development boards in the Microchip AT91 family: SAMA5D3-EDS

selftests/vm: use top_srcdir instead of recomputing relative paths
In various places both in t/t/s/v/Makefile as well as some of the test
sources, we were referring to headers or directories using some fairly
long relative paths.
Since we have a working top_srcdir variable though, which refers to the
root of the kernel tree, we can clean up all of these "up and over"
relative paths, just relying on the single variable instead.

Similar to the issue resolved by commit
0072dc1b53c3 ("arm64: avoid
BUILD_BUG_ON() in alternative-macros"), there is a circular include
dependency through <linux/bits.h> when CONFIG_LTO is enabled due to
<asm/rwonce.h> appearing in the include chain before the contents of
<asm/alternative-macros.h>, which results in ALTERNATIVE() not getting
expanded properly because it has not been defined yet.
Avoid this issue by including <vdso/bits.h>, which includes the
definition of the BIT() macro, instead of <linux/bits.h>, as BIT() is the
only macro from bits.h that is relevant to this header.

Share config response may contain the share name without casefolding as
it is known to the user space daemon. When it is present, casefold and
compare it to the share name the share config request was made with. If
they differ, we have a share config which is incompatible with the way
share config caching is done. This is the case when CONFIG_UNICODE is
not set, the share name contains non-ASCII characters, and those non-
ASCII characters do not match those in the share name known to user

Case-insensitive file name lookups with __caseless_lookup() use

Fix this by using utf8_strncasecmp() if CONFIG_UNICODE is set. On

Pull networking updates from Jakub Kicinski:
"Core:
- Introduce and use a single page frag cache for allocating small skb
heads, clawing back the 10-20% performance regression in UDP flood
test from previous fixes.
- Run packets which already went thru HW coalescing thru SW GRO. This
significantly improves TCP segment coalescing and simplifies
deployments as different workloads benefit from HW or SW GRO.
- Shrink the size of the base zero-copy send structure.
- Move TCP init under a new slow / sleepable version of DO_ONCE().
BPF:
- Add BPF-specific, any-context-safe memory allocator.
- Add helpers/kfuncs for PKCS#7 signature verification from BPF
programs.
- Define a new map type and related helpers for user space -> kernel
communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).
- Allow targeting BPF iterators to loop through resources of one
task/thread.
- Add ability to call selected destructive functions. Expose
crash_kexec() to allow BPF to trigger a kernel dump. Use
CAP_SYS_BOOT check on the loading process to judge permissions.
- Enable BPF to collect custom hierarchical cgroup stats efficiently
by integrating with the rstat framework.
- Support struct arguments for trampoline based programs. Only
structs with size <= 16B and x86 are supported.
- Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
sockets (instead of just TCP and UDP sockets).
- Add a helper for accessing CLOCK_TAI for time sensitive network
related programs.
- Support accessing network tunnel metadata's flags.
- Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.
- Add support for writing to Netfilter's nf_conn:mark.
Protocols:
- WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation
(MLO) work (802.11be, WiFi 7).
- vsock: improve support for SO_RCVLOWAT.
- SMC: support SO_REUSEPORT.
- Netlink: define and document how to use netlink in a "modern" way.
Support reporting missing attributes via extended ACK.
- IPSec: support collect metadata mode for xfrm interfaces.
- TCPv6: send consistent autoflowlabel in SYN_RECV state and RST
packets.
- TCP: introduce optional per-netns connection hash table to allow
better isolation between namespaces (opt-in, at the cost of memory
and cache pressure).
- MPTCP: support TCP_FASTOPEN_CONNECT.
- Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.
- Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.
- Open vSwitch:
- Allow specifying ifindex of new interfaces.
- Allow conntrack and metering in non-initial user namespace.
- TLS: support the Korean ARIA-GCM crypto algorithm.
- Remove DECnet support.
Driver API:
- Allow selecting the conduit interface used by each port in DSA
switches, at runtime.
- Ethernet Power Sourcing Equipment and Power Device support.
- Add tc-taprio support for queueMaxSDU parameter, i.e. setting per
traffic class max frame size for time-based packet schedules.
- Support PHY rate matching - adapting between differing host-side
and link-side speeds.
- Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.
- Validate OF (device tree) nodes for DSA shared ports; make
phylink-related properties mandatory on DSA and CPU ports.
Enforcing more uniformity should allow transitioning to phylink.
- Require that flash component name used during update matches one of
the components for which version is reported by info_get().
- Remove "weight" argument from driver-facing NAPI API as much as
possible. It's one of those magic knobs which seemed like a good
idea at the time but is too indirect to use in practice.
- Support offload of TLS connections with 256 bit keys.
