From ac7c5a688f81c01065e7545313c909dc20d2837b Mon Sep 17 00:00:00 2001 From: Hannes Reinecke <hare@suse.de> Date: Thu, 31 Jul 2008 11:31:15 +0200 Subject: [PATCH] Add SLES10 SP2 compat MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit Hi Mike, due to popular demand I've cranked together a SLES10 SP2 compat patch. You'll have to build it with make KSRC=/usr/src/linux KBUILD_OUTPUT=/usr/src/linux-obj/<arch>/<flavour> Can you add it to the git tree? Thanks, Hannes -- Dr. Hannes Reinecke zSeries & Storage hare@suse.de +49 911 74053 688 SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg GF: Markus Rex, HRB 16746 (AG Nürnberg) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.

Hence we need our own compat patch to deal with this.
