fs: port i_{g,u}id_into_vfs{g,u}id() to mnt_idmap Convert to struct mnt_idmap. Remove legacy file_mnt_user_ns() and mnt_user_ns(). Last cycle we merged the necessary infrastructure in 256c8aed2b42 ("fs: introduce dedicated idmap type for mounts"). This is just the conversion to struct mnt_idmap. Currently we still pass around the plain namespace that was attached to a mount. This is in general pretty convenient but it makes it easy to conflate namespaces that are relevant on the filesystem with namespaces that are relevent on the mount level. Especially for non-vfs developers without detailed knowledge in this area this can be a potential source for bugs. Once the conversion to struct mnt_idmap is done all helpers down to the really low-level helpers will take a struct mnt_idmap argument instead of two namespace arguments. This way it becomes impossible to conflate the two eliminating the possibility of any bugs. All of the vfs and all filesystems only operate on struct mnt_idmap.

ksmbd: add user namespace support For user namespace support, call vfs functions with struct user_namespace got from struct path. This patch have been tested mannually as below. Create an id-mapped mount using the mount-idmapped utility (https://github.com/brauner/mount-idmapped). $ mount-idmapped --map-mount b:1003:1002:1 /home/foo <EXPORT DIR>/foo (the user, "foo" is 1003, and the user "bar" is 1002). And mount the export directory using cifs with the user, "bar". succeed to create/delete/stat/read/write files and directory in the <EXPORT DIR>/foo. But fail with a bind mount for /home/foo.
