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

filemap_invalidate_pages(), which takes a argument indicating whether it
should be non-blocking and might return -EAGAIN.

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.

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()

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

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.

Pull USB fixes from Greg KH:
 "Here are a handful of small USB fixes for 6.11-rc7. Included in here
  are:

   - dwc3 driver fixes for two reported problems

   - two typec ucsi driver fixes

   - cdns2 controller reset fix

  All of these have been in linux-next this week with no reported
  problems"

Pull clk fixes from Stephen Boyd:
 "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"
