Subject: [GIT PULL for v6.11] vfs mount api
Hey Linus,
/* Summary */
This contains work for the mount api:
- Add a generic helper to parse uid and gid mount options. Currently we
open-code the same logic in various filesystems which is error prone.
Especially since the verification of uid and gid mount options is a sensitive
operation in the face of idmappings. Add a generic helper and convert all
filesystems over to it. Make sure that filesystems that are mountable in
unprivileged containers verify that the specified uid and gid can be
represented in the owning namespace of the filesystem.
- Convert hostfs to the new mount api.
/* Testing */
clang: Debian clang version 16.0.6 (26)
gcc: (Debian 13.2.0-24)
All patches are based on v6.10-rc1 and have been sitting in linux-next.
No build failures or warnings were observed.
/* Conflicts */
No known conflicts.
