I guess I'm not seeing what there is to propagate. If the vfsmount we are moving is mounted under a vfsmount that's in a p-node, then there'd be something to propagate, but since the --move doesn't change the structure of mounts underneath the moved mountpoint, I wouldn't expect any changes to be propagated from it to other mountpoints. I must be missing something fundamental.... --Bruce Fields - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
