Btrfs: add qgroup inheritance
When creating a subvolume or snapshot, it is necessary to initialize the qgroup account with a copy of some other (tracking) qgroup. This patch adds parameters to the ioctls to pass the information from which qgroup to inherit. Signed-off-by: Arne Jansen <sensille@gmx.net>
