        Main diffstat here is the re-deletion of netx. I messed up and most
        likely didn't remove the files from the index when I test-merged this
        and saw conflicts, and from there on out 'git rerere' remembered the
        mistake and I missed checking it. Here it's done again as expected.

      	We need to drop everything we remove from the tree, whether
      mnt_has_parent() is true or not.  Usually the bug manifests as a slow
      memory leak (leaked struct mount for initramfs); it becomes much more
      visible in mount_subtree() users, such as btrfs.  There we leak
      a struct mount for btrfs superblock being mounted, which prevents
      fs shutdown on subsequent umount.

      Naohiro Aota authored
      btrfs_lock_and_flush_ordered_range() loads given "*cached_state" into
      cachedp, which, in general, is NULL. Then, lock_extent_bits() updates
      "cachedp", but it never goes backs to the caller. Thus the caller still
      see its "cached_state" to be NULL and never free the state allocated
      under btrfs_lock_and_flush_ordered_range(). As a result, we will
      see massive state leak with e.g. fstests btrfs/005. Fix this bug by
      properly handling the pointers.
