gfs2: Automatically set GFS2_DIF_SYSTEM flag on system files
When new files and directories are created inside a parent directory we automatically inherit the GFS2_DIF_SYSTEM flag (if set) and assign it to the new file/dirs. All new system files/dirs created in the metafs by, say gfs2_jadd, will have this flag set because they will have parent directories in the metafs whose GFS2_DIF_SYSTEM flag has already been set (most likely by a previous mkfs.gfs2) Signed-off-by: Abhi Das <adas@redhat.com> Signed-off-by: Bob Peterson <rpeterso@redhat.com>
