Subject: [PATCH 08/15] btrfs-progs: fix extent key endian bug in repair
Date: Wed, 14 Aug 2013 16:16:38 -0700	[thread overview]
Message-ID: <1376522205-16992-9-git-send-email-zab@redhat.com> (raw)
In-Reply-To: <1376522205-16992-1-git-send-email-zab@redhat.com>

Extents rebuilt from backrefs can have their objectid mangled.  The code
tried to build a disk_key by hand and got the swabbing backwards.
