From 680a34eeb8f2d455121c67697fca146440e61612 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Tue, 6 Jul 2010 10:58:03 +0200 Subject: [PATCH] scsi: Fix SCSI bus reset When the controller raises the SCSI reset line, we have to perform the requested reset on all disks attached to the controller's bus. Moreover, reset is edge triggered, so avoid repeating it if the line was already high.
