Merge tag '9p-for-7.2-rc1' of https://github.com/martinetd/linux

Pull 9p updates from Dominique Martinet:
 "Asides of the avalanche of LLM-driven fixes, there are a couple of big
  changes this cycle:

   - negative dentry and symlink cache

   - a way out of the unkillable "io_wait_event_killable" (because it
     looped around waiting for the request flush to come back from
     server; this has been bugging syzcaller folks since forever): I'm
     still not 100% sure about this patch, but I think it's as good as
     we'll ever get, and will keep testing a bit further in the coming
     weeks

  The rest is more noisy than usual, but shouldn't cause any trouble"
