umount(2) is not the only way for mount to detached from a mountpoint. There's exit(2) as well - when the last process in a namespace exits, it gets dissolved. What should happen upon those? Even more interesting question is what should happen if you do such mount, then clone a process into a new namespace and have it exit. Should _that_ rmdir the hell out of that mountpoint (presumably detaching everything mounted on it in all namespaces)? What should happen when a process in new namespace decides to unmount that thing, because they don't what it visible. Should that take out the instance in parent namespace? ` -- 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/
