io-wq: make buffered file write hashed work map per-ctx
Before the io-wq thread change, we maintained a hash work map and lock
per-node per-ring. That wasn't ideal, as we really wanted it to be per
ring. But now that we have per-task workers, the hash map ends up being
just per-task. That'll work just fine for the normal case of having
one task use a ring, but if you share the ring between tasks, then it's
considerably worse than it was before.
Make the hash map per ctx instead, which provides full per-ctx buffered
write serialization on hashed writes.

There's a small window between lookup dropping the reference to the

These races have always been there, they are just more apparent now that
we do early cancel of io-wq when the task exits.
Ensure that the io-wq manager sets task state correctly to not miss
wakeups for task creation. This is important if we get a wakeup after

schedule() a no-op. Also increment the wq ref count before forking the

"x86:
- Support for userspace to emulate Xen hypercalls
- Raise the maximum number of user memslots
- Scalability improvements for the new MMU.
Instead of the complex "fast page fault" logic that is used in
mmu.c, tdp_mmu.c uses an rwlock so that page faults are concurrent,
but the code that can run against page faults is limited. Right now
only page faults take the lock for reading; in the future this will
be extended to some cases of page table destruction. I hope to
switch the default MMU around 5.12-rc3 (some testing was delayed
due to Chinese New Year).

Merge tag 'sched-core-2021-02-17' of git://git./linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar:
"Core scheduler updates:
- Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the
preempt=none/voluntary/full boot options (default: full), to allow
distros to build a PREEMPT kernel but fall back to close to
PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling behavior via
a boot time selection.
There's also the /debug/sched_debug switch to do this runtime.
This feature is implemented via runtime patching (a new variant of
static calls).
The scope of the runtime patching can be best reviewed by looking
at the sched_dynamic_update() function in kernel/sched/core.c.
( Note that the dynamic none/voluntary mode isn't 100% identical,
for example preempt-RCU is available in all cases, plus the
preempt count is maintained in all models, which has runtime
overhead even with the code patching. )
The PREEMPT_VOLUNTARY/PREEMPT_NONE models, used by the vast
majority of distributions, are supposed to be unaffected.
- Fix ignored rescheduling after rcu_eqs_enter(). This is a bug that
was found via rcutorture triggering a hang. The bug is that
rcu_idle_enter() may wake up a NOCB kthread, but this happens after
the last generic need_resched() check. Some cpuidle drivers fix it
by chance but many others don't.
In true 2020 fashion the original bug fix has grown into a 5-patch
scheduler/RCU fix series plus another 16 RCU patches to address the
underlying issue of missed preemption events. These are the initial
fixes that should fix current incarnations of the bug.
- Clean up rbtree usage in the scheduler, by providing & using the
following consistent set of rbtree APIs:
partial-order; less() based:
- rb_add(): add a new entry to the rbtree
- rb_add_cached(): like rb_add(), but for a rb_root_cached
total-order; cmp() based:
- rb_find(): find an entry in an rbtree
- rb_find_add(): find an entry, and add if not found
- rb_find_first(): find the first (leftmost) matching entry
- rb_next_match(): continue from rb_find_first()
- rb_for_each(): iterate a sub-tree using the previous two
- Improve the SMP/NUMA load-balancer: scan for an idle sibling in a
single pass. This is a 4-commit series where each commit improves
one aspect of the idle sibling scan logic.
- Improve the cpufreq cooling driver by getting the effective CPU
utilization metrics from the scheduler
- Improve the fair scheduler's active load-balancing logic by
reducing the number of active LB attempts & lengthen the
load-balancing interval. This improves stress-ng mmapfork
performance.
- Fix CFS's estimated utilization (util_est) calculation bug that can
result in too high utilization values
Misc updates & fixes:
- Fix the HRTICK reprogramming & optimization feature
- Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code
- Reduce dl_add_task_root_domain() overhead
- Fix uprobes refcount bug
- Process pending softirqs in flush_smp_call_function_from_idle()

Pull xfs updates from Darrick Wong:
"There's a lot going on this time, which seems about right for this
drama-filled year.
Community developers added some code to speed up freezing when
read-only workloads are still running, refactored the logging code,
added checks to prevent file extent counter overflow, reduced iolock
cycling to speed up fsync and gc scans, and started the slow march
towards supporting filesystem shrinking.
There's a huge refactoring of the internal speculative preallocation
garbage collection code which fixes a bunch of bugs, makes the gc
scheduling per-AG and hence multithreaded, and standardizes the retry
logic when we try to reserve space or quota, can't, and want to
trigger a gc scan. We also enable multithreaded quotacheck to reduce
mount times further. This is also preparation for background file gc,
which may or may not land for 5.13.
We also fixed some deadlocks in the rename code, fixed a quota
accounting leak when FSSETXATTR fails, restored the behavior that
write faults to an mmap'd region actually cause a SIGBUS, fixed a bug
where sgid directory inheritance wasn't quite working properly, and
fixed a bug where symlinks weren't working properly in ecryptfs. We
also now advertise the inode btree counters feature that was
introduced two cycles ago.
Summary:
- Fix an ABBA deadlock when renaming files on overlayfs.
- Make sure that we can't overflow the inode extent counters when
adding to or removing extents from a file.
- Make directory sgid inheritance work the same way as all the other
filesystems.
- Don't drain the buffer cache on freeze and ro remount, which should
reduce the amount of time if read-only workloads are continuing
during the freeze.
- Fix a bug where symlink size isn't reported to the vfs in ecryptfs.
- Disentangle log cleaning from log covering. This refactoring sets
us up for future changes to the log, though for now it simply means
that we can use covering for freezes, and cleaning becomes
something we only do at unmount.
- Speed up file fsyncs by reducing iolock cycling.
- Fix delalloc blocks leaking when changing the project id fails
because of input validation errors in FSSETXATTR.
- Fix oversized quota reservation when converting unwritten extents
during a DAX write.
- Create a transaction allocation helper function to standardize the
idiom of allocating a transaction, reserving blocks, locking
inodes, and reserving quota. Replace all the open-coded logic for
file creation, file ownership changes, and file modifications to
use them.
- Actually shut down the fs if the incore quota reservations get
corrupted.
- Fix background block garbage collection scans to not block and to
actually clean out CoW staging extents properly.
- Run block gc scans when we run low on project quota.
- Use the standardized transaction allocation helpers to make it so
that ENOSPC and EDQUOT errors during reservation will back out,
invoke the block gc scanner, and try again. This is preparation for
introducing background inode garbage collection in the next cycle.
- Combine speculative post-EOF block garbage collection with
speculative copy on write block garbage collection.
- Enable multithreaded quotacheck.
- Allow sysadmins to tweak the CPU affinities and maximum concurrency
levels of quotacheck and background blockgc worker pools.
- Expose the inode btree counter feature in the fs geometry ioctl.
- Cleanups of the growfs code in preparation for starting work on
filesystem shrinking.
- Fix all the bloody gcc warnings that the maintainer knows about. :P
- Fix a RST syntax error.
- Don't trigger bmbt corruption assertions after the fs shuts down.
- Restore behavior of forcing SIGBUS on a shut down filesystem when
someone triggers a mmap write fault (or really, any buffered
write)"

concurrent checkpoint requests as much as possible to eliminate
redundant checkpoint issues. Plus, we can eliminate the sluggish issue
caused by slow checkpoint operation when the checkpoint is done in a
process context in a cgroup having low i/o budget and cpu shares.
Enhancements:
- add compress level for lz4 and zstd in mount option
- checkpoint_merge mount option
- deprecate f2fs_trace_io
Bug fixes:
- flush data when enabling checkpoint back
- handle corner cases of mount options
- missing ACL update and lock for I_LINKABLE flag
- attach FIEMAP_EXTENT_MERGED in f2fs_fiemap
- fix potential deadlock in compression flow
- fix wrong submit_io condition
As usual, we've cleaned up many code flows and fixed minor bugs"

Pull btrfs updates from David Sterba:
"This brings updates of space handling, performance improvements or bug
fixes. The subpage block size and zoned mode features have reached
state where they're usable but with limitations.
Performance or related:
- do not block on deleted block group mutex in the cleaner, avoids
some long stalls
- improved flushing: make it work better with ticket space
reservations and avoid excessive transaction commits in some
scenarios, slightly improves throughput for random write load
- preemptive background flushing: separate the logic from ticket
reservations, improve the accounting and decisions when to flush in
low space conditions
- less lock contention related to running delayed refs, let just one
thread do the flushing when there are many inside transaction
commit
- dbench workload improvements: avoid unnecessary work when logging
inodes, fewer fallbacks to transaction commit and thus less waiting
for it (+7% throughput, -20% latency)
Core:
- subpage block size
- currently read-only support
- refactor and generalize code where sectorsize is assumed to be
page size, add the subpage handling everywhere
- the read-write support is on the way, page sizes are still
limited to 4K or 64K
- zoned mode, first working version but with limitations
- SMR/ZBC/ZNS friendly allocation mode, utilizing the "no fixed
location for structures" and chunked allocation
- superblock as the only fixed data structure needs special
handling, uses 2 consecutive zones as a ring buffer
- tree-log support with a dedicated block group to avoid unordered
writes
- emulated zones on non-zoned devices
- not yet working
- all non-single block group profiles, requires more zone write
pointer synchronization between the multiple block groups
- fitrim due to dependency on space cache, can be implemented
Fixes:
- ref-verify: proper tree owner and node level tracking
- fix pinned byte accounting, causing some early ENOSPC now more
likely due to other changes in delayed refs
Other:
- error handling fixes and improvements
- more error injection points
- more function documentation
- more and updated tracepoints
- subset of W=1 checked by default
- update comments to allow more automatic kdoc parameter checks"

tty: protect tty_write from odd low-level tty disciplines
Al root-caused a new warning from syzbot to the ttyprintk tty driver
returning a write count larger than the data the tty layer actually gave
it. Which confused the tty write code mightily, and with the new
iov_iter based code, caused a WARNING in iov_iter_revert().
syzbot correctly bisected the source of the new warning to commit

- zx - added in 2015 for both 32, 2017 for 64 bit, no notable changes
- arch/c6x - added in 2011, but work stalled soon after that

io_uring: keep generic rsrc infra generic
io_rsrc_ref_quiesce() is a generic resource function, though now it
was wired to allocate and initialise ref nodes with file-specific
callbacks/etc. Keep it sane by passing in as a parameters everything we
need for initialisations, otherwise it will hurt us badly one day.
