From 5d5ff44fe6775ccb922fd1f7d478b2ba9ca95068 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 3 Jun 2006 13:21:13 +0200 Subject: [SCSI] fix up request buffer reference in various scsi drivers Various scsi drivers use scsi_cmnd.buffer and scsi_cmnd.bufflen in their queuecommand functions. Those fields are internal storage for the midlayer only and are used to restore the original payload after request_buffer and request_bufflen have been overwritten for EH. Using the buffer and bufflen fields means they do very broken things in error handling.
