[opensuse-kernel] Concurrent mounting of btrfs subvolumes
by Andrey Borzenkov 15 Oct '13

15 Oct '13

Is it possible to concurrently mount different btrfs subvolumes at the same time? Neither /proc/self/mounts nor /proc/self/mountinfo return information about subvol=/subvolid= option. What is fool proof way to determine which subvolume is actually mounted? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org
