Merge tag '9p-fixes-6.5-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs

Pull 9p fixes from Eric Van Hensbergen:
 "Misc set of fixes for 9p.

  Most of these clean up warnings we've gotten out of compilation tools,
  but several of them were from inspection while hunting down a couple
  of regressions.

  The most important one is 75b396821cb7 ("fs/9p: remove unnecessary and
  overrestrictive check") which caused a regression for some folks by
  restricting mmap in any case where writeback caches weren't enabled.

  Most of the other bugs caught via inspection were type mismatches"
