In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix root leak if its reloc root is unexpected in merge_reloc_roots()
If we have an unexpected reloc_root for our root, we jump to the out label
but never drop the reference we obtained for root, resulting in a leak.
Add a missing btrfs_put_root() call.
