To be able to nuke simple quotas entirely if you decide you don't want
them (and especially the OWNER_REFs) in your filesystem after all.

If you run
btrfstune --remove-simple-quota <dev>
on an unmounted filesystem, it will be as if simple quotas never existed
on that filesystem.

Boris Burkov (3):
  btrfs-progs: add a helper for clearing all the items in a tree
  btrfs-progs: btrfstune: fix documentation for --enable-simple-quota
  btrfs-progs: btrfstune: add ability to remove squotas
