Merge tag '9p-for-6.1' of https://github.com/martinetd/linux

Pull 9p updates from Dominique Martinet:
 "Smaller buffers for small messages and fixes.

  The highlight of this is Christian's patch to allocate smaller buffers
  for most metadata requests: 9p with a big msize would try to allocate
  large buffers when just 4 or 8k would be more than enough; this brings
  in nice performance improvements.

  There's also a few fixes for problems reported by syzkaller (thanks to
  Schspa Shi, Tetsuo Handa for tests and feedback/patches) as well as
  some minor cleanup"
