From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Fri, 13 Jul 2007 18:35:57 +0900 From: Paul Mundt Subject: [PATCH] slob: sparsemem support. Message-ID: <20070713093557.GA3403@linux-sh.org> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Sender: owner-linux-mm@kvack.org Return-Path: To: Andrew Morton Cc: Yasunori Goto , Matt Mackall , linux-mm@kvack.org List-ID: Currently slob is disabled if we're using sparsemem, due to an earlier patch from Goto-san. Slob and static sparsemem work without any trouble as it is, and the only hiccup is a missing slab_is_available() in the case of sparsemem extreme. With this, we're rid of the last set of restrictions for slob usage.
