From 6bdf131fac2336adb1a628f992ba32384f653a55 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 2 Sep 2016 15:25:43 -0400 Subject: Btrfs: don't leak reloc root nodes on error 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.
