Subject: [PATCH 10/15] btrfs-progs: fix qgroup realloc inheritance
Date: Wed, 14 Aug 2013 16:16:40 -0700 [thread overview]
Message-ID: <1376522205-16992-11-git-send-email-zab@redhat.com> (raw)
In-Reply-To: <1376522205-16992-1-git-send-email-zab@redhat.com>
qgroup.c:82:23: warning: memcpy with byte count of 0
qgroup.c:83:23: warning: memcpy with byte count of 0
The inheritance wasn't copying qgroups[] because a confused sizeof()
gave 0 byte memcpy()s. It's been like this for the year since it was
merged, so I guess this isn't a very important thing to do :).
