[GIT PULL] vfs pagecache

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

/* Summary */

Cleanup filesystem page flag usage: This continues the work to make the
mappedtodisk/owner_2 flag available to filesystems which don't use
buffer heads. Further patches remove uses of Private2. This brings us
very close to being rid of it entirely.

/* Testing */

gcc version 14.2.0 (Debian 14.2.0-6)
Debian clang version 16.0.6 (27+b1)

All patches are based on v6.12-rc1 and have been sitting in linux-next.
No build failures or warnings were observed.
