Merge tag '9p-for-6.12-rc4' of https://github.com/martinetd/linux
Pull 9p fixes from Dominique Martinet:
"Mashed-up update that I sat on too long:
- fix for multiple slabs created with the same name
- enable multipage folios
- theorical fix to also look for opened fids by inode if none was
found by dentry"
[ Enabling multi-page folios should have been done during the merge
window, but it's a one-liner, and the actual meat of the enablement
is in netfs and already in use for other filesystems... - Linus ]

9p: Avoid creating multiple slab caches with the same name
