Can't btrfs just set the immutable flag on every inode that is read when the root has the BTRFS_ROOT_SUBVOL_RDONLY flag? That would cut down the places that need this check to the ioctl path so that we prevent users from clearling the immutable flag. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
