cifs: on multiuser mount, set ownership to current_fsuid/current_fsgid (try #7) (1c456013) · Commits · 戴 / test

commit made cifs_getattr set the ownership of files to current_fsuid/current_fsgid when multiuser mounts were in use and when mnt_uid/mnt_gid were non-zero. It should have instead based that decision on the CIFS_MOUNT_OVERR_UID/GID flags. Signed-off-by:
