Subject: [PATCH] io_submit.2: acknowledge possibility of short return
Date: Thu,  7 Sep 2017 16:44:28 -0400	[thread overview]
Message-ID: <20170907204428.8344-1-sage@redhat.com> (raw)

Note that the return value may be a value less than nr
if not all iocbs were queued at once.  This would have saved
me an embarrassing amount of time.
