f2fs: support norecovery mount option
This patch adds a mount option, norecovery, which is mostly same as disable_roll_forward. The only difference is that norecovery should be activated with read-only mount option. This can be used when user wants to check whether f2fs is mountable or not without any recovery process. (e.g., xfstests/200) Reviewed-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
