Subject: [Qemu-devel] [PATCH] linux-aio: Fix laio_submit error handling
Date: Thu, 22 Sep 2011 14:24:38 +0200 [thread overview]
Message-ID: <1316694278-4265-1-git-send-email-kwolf@redhat.com> (raw)
The error handling order was in the wrong order, so that either the ACB would
be leaked or the counter would be decremented when it shouldn't.
