Axel Burri cb5e361f7a btrbk: add --rootid command option for "btrfs subvolume show" 2018-07-09 16:13:00 +02:00
Axel Burri b37ef84e36 btrbk: always read mountpoints; include all snapshots from mountpoint as candidates for best common parent
Dropped readin of subvolid and realpath by btrfs_subvolume_show(), we
now always read /proc/self/mounts (and call readlink).

When picking the best common parent in get_best_parent(), we want to
list as many snapshots as possible. For now, we list all from the
mountpoint of snaproot ($sroot/<snapshot_dir>), due to a bug in
btrfs-progs [1]. Also added code (commented out) to list snapshots
from all known mountpoints.
