From 29982e9acd3e81a289c73321401427d02eaa8adc Mon Sep 17 00:00:00 2001 From: Doug Chapman Date: Mon, 7 May 2007 15:59:46 -0400 Subject: [SCSI] fusion: fix for BZ 8426 - massive slowdown on SCSI CD/DVD drive Patch for: http://bugzilla.kernel.org/show_bug.cgi?id=8426 A recent code cleanup that moved code from mptscsih to mptspi inadvertently change the order some code was called. This caused a massive slowdown (of 150x to 300x) on the CD/DVD drive on the high-end HP Integrity servers.
