50c52250e2 block: implement async io_uring discard cmd
io_uring allows implementing custom file specific asynchronous
operations via the fops->uring_cmd callback, a.k.a. IORING_OP_URING_CMD
requests or just io_uring commands. Use it to add support for async
discards.

Normally, it first tries to queue up bios in a non-blocking context,
and if that fails, we'd retry from a blocking context by returning
-EAGAIN to the core io_uring. We always get the result from bios
asynchronously by setting a custom bi_end_io callback, at which point
we drag the request into the task context to either reissue or complete
it and post a completion to the user.

Unlike ioctl(BLKDISCARD) with stronger guarantees against races, we only
do a best effort attempt to invalidate page cache, and it can race with
any writes and reads and leave page cache stale. It's the same kind of
races we allow to direct writes.

Also, apart from cases where discarding is not allowed at all, e.g.
discards are not supported or the file/device is read only, the user
should assume that the sector range on disk is not valid anymore, even
when an error was returned to the user.

a12c883a0a filemap: introduce filemap_invalidate_pages
kiocb_invalidate_pages() is useful for the write path, however not
everything is backed by kiocb and we want to reuse the function for bio
based discard implementation. Extract and and reuse a new helper called
filemap_invalidate_pages(), which takes a argument indicating whether it
should be non-blocking and might return -EAGAIN.

6746ee4c3a io_uring/cmd: expose iowq to cmds
When an io_uring request needs blocking context we offload it to the
io_uring's thread pool called io-wq. We can get there off ->uring_cmd
by returning -EAGAIN, but there is no straightforward way of doing that
from an asynchronous callback. Add a helper that would transfer a
command to a blocking context.

Note, we do an extra hop via task_work before io_queue_iowq(), that's a
limitation of io_uring infra we have that can likely be lifted later
if that would ever become a problem.

84eacf177f io_uring/io-wq: inherit cpuset of cgroup in io worker
The io worker threads are userland threads that just never exit to the
userland. By that, they are also assigned to a cgroup (the group of the
creating task).

When creating a new io worker, this worker should inherit the cpuset

ed9832bc08 block: introduce folio awareness and add a bigger size from folio
Add a bigger size from folio to bio and skip merge processing for pages.

Fetch the offset of page within a folio. Depending on the size of folio
and folio_offset, fetch a larger length. This length may consist of
multiple contiguous pages if folio is multiorder.

Using the length calculate number of pages which will be added to bio and
increment the loop counter to skip those pages.

This technique helps to avoid overhead of merging pages which belong to
same large order folio.

Also folio-ize the functions bio_iov_add_page() and
bio_iov_add_zone_append_page()

29390bb566 blk-throttle: support prioritized processing of metadata
Currently, blk-throttle handle all IO fifo, hence if data IO is
throttled and then meta IO is dispatched, the meta IO will have to wait
for the data IO, causing priority inversion problems.

This patch support to handle metadata first and then pay debt while
throttling data.

Test script: use cgroup v1 to throttle root cgroup, then create new
dir and file while write back is throttled

test() {
  mkdir /mnt/test/xxx
  touch /mnt/test/xxx/1
  sync /mnt/test/xxx
  sync /mnt/test/xxx

Some file systems, ocfs2 in this case, will return -EOPNOTSUPP for

correct, the usual return value for something that requires blocking
issue is -EAGAIN.

A refactoring io_uring commit dropped calling kiocb_done() for
negative return values, which is otherwise where we already do that
transformation. To ensure we catch it in both spots, check it in
__io_read() itself as well.

Pull bcachefs fixes from Kent Overstreet:

 - fix ca->io_ref usage; analagous to previous patch doing that for main
   discard path

 - cond_resched() in __journal_keys_sort(), cutting down on "hung task"
   warnings when journal is big

 - rest of basic BCH_SB_MEMBER_INVALID support

 - and the critical one: don't delete open files in online fsck, this
   was causing the "dirent points to inode that doesn't point back"

f011c9cf04 io_uring/sqpoll: do not allow pinning outside of cpuset
The submit queue polling threads are userland threads that just never
exit to the userland. When creating the thread with IORING_SETUP_SQ_AFF,
the affinity of the poller thread is set to the cpu specified in
sq_thread_cpu. However, this CPU can be outside of the cpuset defined
by the cgroup cpuset controller. This violates the rules defined by the
cpuset controller and is a potential issue for realtime applications.

In b7ed6d8ffd6 we fixed the default affinity of the poller thread, in
case no explicit pinning is required by inheriting the one of the
creating task. In case of explicit pinning, the check is more
complicated, as also a cpu outside of the parent cpumask is allowed.
We implemented this by using cpuset_cpus_allowed (that has support for
cgroup cpusets) and testing if the requested cpu is in the set.

0e0bcf07ec io_uring/eventfd: move refs to refcount_t
atomic_t for the struct io_ev_fd references and there are no issues with
it. While the ref getting and putting for the eventfd code is somewhat
performance critical for cases where eventfd signaling is used (news
flash, you should not...), it probably doesn't warrant using an atomic_t
for this. Let's just move to it to refcount_t to get the added
protection of over/underflows.

d1f2d51b71 A pile of Qualcomm clk driver fixes with two main themes: the alpha PLL
driver and shared RCGs, and one fix for the Starfive JH7110 SoC.
 
  - The Alpha PLL clk_ops had multiple problems around setting rates.
    There are a handful of patches here that fix masks and skip enabling
    the clk from set_rate() when the PLL is disabled. The PLLs are
    crucial to operation of the system as almost all frequencies in the
    system are derived from them.
 
  - Parking shared RCGs at a slow always on clk at registration time
    breaks stuff. USB host mode can't handle such a slow frequency and
    the serial console gets all garbled when the UART clk is handed over
    to the kernel. There's a few patches that don't use the shared
    clk_ops for the UART clks and another one to skip parking the USB clk
    at registration time.
 
  - The Starfive PLL driver used for the CPU was busted causing cpufreq
    to fail because the clk didn't change to a safe parent during
    set_rate(). The fix is to register a notifier and switch to a safe
    parent so the PLL can change rate in a glitch free manner.

acc8c0a988 blk-mq: add missing unplug trace event
The single-queue optimized list flush doesn't have an unplug trace event
to pair with the plug event. Add one.

In the unlikely event an error occurs and falls back to the less
optimized plug flush path, it's possible a 2nd unplug trace event will
be logged, but it will show the remainig count that weren't previously
handled.

a02e98bebc mtip32xx: Remove redundant null pointer checks in mtip_hw_debugfs_init()
Since the debugfs_create_dir() never returns a null pointer, checking
the return value for a null pointer is redundant. Since
debugfs_create_file() can deal with a ERR_PTR() style pointer, drop
the check.  Since mtip_hw_debugfs_init does not pay attention to the
return value, its return type can be changed to void.

9d4c304001 KVM: x86: don't fall through case statements without annotations
clang warns on this because it has an unannotated fall-through between
cases:

   arch/x86/kvm/x86.c:4819:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]

and while we could annotate it as a fallthrough, the proper fix is to
just add the break for this case, instead of falling through to the
default case and the break there.

gcc also has that warning, but it looks like gcc only warns for the
cases where they fall through to "real code", rather than to just a
break.  Odd.
