From 8a7d656f3dfb7889316ba57502f1eaa6106fd6f8 Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Thu, 10 Dec 2015 11:08:59 +0000 Subject: [PATCH] Btrfs: fix transaction handle leak in balance If we fail to allocate a new data chunk, we were jumping to the error path without release the transaction handle we got before. Fix this by always releasing it before doing the jump.
