Subject: [patch] Btrfs: silence a compiler warning
Date: Wed, 22 Feb 2012 10:30:55 +0300 [thread overview]
Message-ID: <20120222073055.GB7389@elgon.mountain> (raw)
Gcc warns that "ret" can be used uninitialized. It can't actually be
used uninitialized because btrfs_num_copies() always returns 1 or more.
