From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Mon, 1 Dec 2008 00:32:04 +0000 (GMT) From: Hugh Dickins Subject: [PATCH 11/9] swapfile: let others seed random In-Reply-To: Message-ID: References: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linux-mm@kvack.org Return-Path: To: Andrew Morton Cc: David Woodhouse , Jens Axboe , Matthew Wilcox , Joern Engel , James Bottomley , Donjun Shin , Tejun Heo , Arjan van de Ven , Matt Mackall , linux-mm@kvack.org, linux-kernel@vger.kernel.org List-ID: Remove the srandom32((u32)get_seconds()) from non-rotational swapon: there's been a coincidental discussion of earlier randomization, assume that goes ahead, let swapon be a client rather than stirring for itself.
