From b2acdddfad13c38a1e8b927d83c3cf321f63601a Mon Sep 17 00:00:00 2001 From: Anand Jain Date: Wed, 7 Oct 2015 17:23:23 +0800 Subject: [PATCH] Btrfs: add missing brelse when superblock checksum fails Looks like oversight, call brelse() when checksum fails. Further down the code, in the non error path, we do call brelse() and so we don't see brelse() in the goto error paths.
