Date: Tue, 10 Oct 2006 21:11:43 +0200 (CEST) From: Stefan Richter <stefanr@...6.in-berlin.de> To: linux1394-devel@...ts.sourceforge.net cc: Jeff Garzik <jeff@...zik.org>, linux-kernel@...r.kernel.org Subject: [PATCH 2.6.19-rc1 1/3] ieee1394: lock smaller region by host_num_alloc mutex We need the mutex only around the iteration over existing hosts. Signed-off-by: Stefan Richter <stefanr@...6.in-berlin.de> --- This prepares hosts.c for the following patch which adds checks of driver core errors.
