From 12265709ac6e197f4d40d9ec1fd3af97b4196a35 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 21 Jul 2008 10:25:52 -0400 Subject: [SCSI] scsi_eh_prep_cmnd should save scmd->underflow This patch (as1116) fixes a bug in scsi_eh_prep_cmnd() and scsi_eh_restore_cmnd(). These routines are supposed to save any values they change and restore them later, but someone forgot to save & restore scmd->underflow. This fixes part of the problem reported in Bugzilla #9638.
