This patch enables idmapped mounts for f2fs, since all dedicated helpers for this functionality existsm, so, in this patch we just pass down the user_namespace argument from the VFS methods to the relevant helpers. Simple idmap example on f2fs image: 1. truncate -s 128M f2fs.img 2. mkfs.f2fs f2fs.img 3. mount f2fs.img /mnt/f2fs/ 4. touch /mnt/f2fs/file 5. ls -ln /mnt/f2fs/ total 0 -rw-r--r-- 1 0 0 0 2月 4 13:17 file 6. ./mount-idmapped --map-mount b:0:1001:1 /mnt/f2fs/ /mnt/scratch_f2fs/ 7. ls -ln /mnt/scratch_f2fs/ total 0 -rw-r--r-- 1 1001 1001 0 2月 4 13:17 file Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
