4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Josef Bacik <jbacik@xxxxxx>
commit 6bdf131fac2336adb1a628f992ba32384f653a55 upstream.
We don't track the reloc roots in any sort of normal way, so the only way the
root/commit_root nodes get free'd is if the relocation finishes successfully and
the reloc root is deleted. Fix this by free'ing them in free_reloc_roots.
Thanks,
