[GIT PULL for v6.16] vfs mount

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

Unfortunately this had to be rebased as this had patches in it who were
also present in another branch under different hashes. Because I both
merged them and exposed them as one set in -next this didn't get
noticed. The patches here are trivial though.

/* Summary */

This contains minor mount updates for this cycle:

- mnt->mnt_devname can never be NULL so simplify the code handling that case.

- Add a comment about concurrent changes during statmount() and listmount().

- Update the STATMOUNT_SUPPORTED macro.

- Convert mount flags to an enum.

/* Testing */

gcc (Debian 14.2.0-19) 14.2.0
Debian clang version 19.1.7 (3)

No build failures or warnings were observed.

/* Conflicts */
