nilfs2: tighten restrictions on inode flags
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. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
