    nilfs2: tighten restrictions on inode flags · b253a3e4
    Ryusuke Konishi authored
    Nilfs has few rectrictions on which flags may be set on which inodes
    like ext2/3/4 filesystems used to be.  Specifically DIRSYNC may only
    be set on directories and IMMUTABLE and APPEND may not be set on
    links.  Tighten that to disallow TOPDIR being set on non-directories
    and only NODUMP and NOATIME to be set on non-regular file,
    non-directories.
    
    This introduces a flags masking function like those of extN and uses
    it during inode creation.
