Subject: [PATCH] aio: Cleanup unnecessary test for nr_pages
Date: Mon, 13 Jun 2016 00:33:54 +0800 [thread overview]
Message-ID: <1465749234-25746-1-git-send-email-mnghuan@gmail.com> (raw)
The variable nr_pages is always more than 1, because the size of
structure aio_ring is bigger than 0. So remove unnecessary test for
nr_page.
