f2fs: add F2FS_INLINE_DOTS to recover missing dot dentries
If f2fs was corrupted with missing dot dentries, it needs to recover them after fsck.f2fs detection. The underlying precedure is: 1. The fsck.f2fs remains F2FS_INLINE_DOTS flag in directory inode, if it detects missing dot dentries. 2. When f2fs looks up the corrupted directory, it triggers f2fs_add_link with proper inode numbers and their dot and dotdot names. 3. Once f2fs recovers the directory without errors, it removes F2FS_INLINE_DOTS finally. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
