Subject: [PATCH 08/29] drbd: rename random32() to prandom_u32()
Date: Mon, 24 Dec 2012 11:13:55 +0900	[thread overview]
Message-ID: <1356315256-6572-9-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1356315256-6572-1-git-send-email-akinobu.mita@gmail.com>

Use more preferable function name which implies using a pseudo-random
number generator.
