Hi Linus,

A few fixes that should go into the 6.13-rc6 release, either fixing
regressions in this cycle, or headed to stable. This pull request
contains:

- Fix an issue with the read multishot support and posting of CQEs from
  io-wq context.

- Fix a regression introduced in this cycle, where making the timeout
  lock a raw one uncovered another locking dependency. As a result, move
  the timeout flushing outside of the timeout lock, punting them to a
  local list first.

- Fix use of an uninitialized variable in io_async_msghdr. Doesn't
  really matter functionally, but silences a valid KMSAN complaint that
  it's not always initialized.

- Fix use of incrementally provided buffers for read on non-pollable
  files, where the buffer always gets committed upfront. Unfortunately
  the buffer address isn't resolved first, so the read ends up using the
  updated rather than the current value.

Please pull!
