From b8803b1cef28af785c4e903b9b1449898d68c758 Mon Sep 17 00:00:00 2001 From: Wayne Boyer Date: Fri, 14 May 2010 08:55:13 -0700 Subject: [PATCH] [SCSI] ipr: set the data list length in the request control block In bring up testing for the new 64 bit adapters, the first read command failed after loading the driver. The cause was that the command requires more than one scatter gather element and the corresponding code to set the data list length in the request control block was missing. This patch adds the correct assignment.
