Gentle ping?

Or we don't need this feature and just let btrfs-check to repair such 
problem?

Thanks,
Qu

Since we're busting ghost subvolumes, the branch is now called

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.

   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
