[PATCH 0/3] btrfs: allow BTRFS_IOC_SNAP_DESTROY_V2 to remove ghost subvolume

[Qu Wenruo <wqu@suse.com>]

Since we're busting ghost subvolumes, the branch is now called
ghost_busters:
https://github.com/adam900710/linux/tree/ghost_busters

The first two patches are just cleanup found during the development.

The first is a missing check for subvolid range, the missing check
itself won't cause any harm, just returning -ENOENT from dentry lookup,
other than the expected -EINVAL.

The 2nd is a super old dead comment from the early age of btrfs.

The final patch is the real work to allow patched "btrfs subvolume delete -i"
to delete ghost subvolume.
Tested with the image dump of previous submitted btrfs-progs patchset.

Qu Wenruo (3):
  btrfs: return -EINVAL if some user wants to remove uuid/data_reloc
    tree
  btrfs: remove dead comment on btrfs_add_dead_root()
  btrfs: allow BTRFS_IOC_SNAP_DESTROY_V2 to remove ghost subvolume
