Oh, that's pretty sweet -- it means there's actually a way to reliably wait for cleaner work to be done on all deleted snapshots before unmounting the FS. I was wondering about that recently for some transient filesystems (which get mounted, synced to, snapshot-created/removed, then unmounted). Now can just loop with a few second sleeps until `btrfs sub list -d $PATH` comes up empty. -- With respect, Roman -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
