Merge tag '9p-for-6.18-rc1' of https://github.com/martinetd/linux
Pull 9p updates from Dominique Martinet:
"A bunch of unrelated fixes:
- polling fix for trans fd that ought to have been fixed otherwise
back in March, but apparently came back somewhere else...
- USB transport buffer overflow fix
- Some dentry lifetime rework to handle metadata update for currently
opened files in uncached mode, or inode type change in cached mode
- a double-put on invalid flush found by syzbot
- and finally /sys/fs/9p/caches not advancing buffer and overwriting
itself for large contents
Thanks to everyone involved!"
