    f2fs: introduce F2FS_FEATURE_LOST_FOUND feature · b7c409de
    Sheng Yong authored
    This patch introduces a new feature, F2FS_FEATURE_LOST_FOUND, which
    is set by mkfs. mkfs creates a directory named lost+found, which saves
    unreachable files. If fsck finds a file which has no parent, or its
    parent is removed by fsck, the file will be placed under lost+found
    directory by fsck.
    
    lost+found directory could not be encrypted. As a result, the root
    directory cannot be encrypted too. So if LOST_FOUND feature is enabled,
    let's avoid to encrypt root directory.
