Subject: [PATCH 1/1] btrfs-progs: fix compiler warning
Date: Thu,  5 Jun 2014 10:13:39 +0200	[thread overview]
Message-ID: <1401956019-2175-1-git-send-email-mail@eworm.de> (raw)

gcc 4.9.0 gives warnings about possibly uninitialized values when
compiling with function inlining and optimization level two enabled
(CFLAGS="-finline-functions -O2").

Initializing the values fixes the warning. Hope this is correct.
