From bbb9d18009373bc74bfeba760097de277f395858 Mon Sep 17 00:00:00 2001 From: James Smart Date: Wed, 10 Jun 2009 17:23:16 -0400 Subject: [PATCH] [SCSI] lpfc 8.3.3 : Add support for Target Reset handler entrypoint Patch was originally submitted upstream on 4/21/2008: http://marc.info/?l=linux-scsi&m=120880973719266&w=2 Somewhere, it never get merged. The patch restructures the task mgmt routines, commonizing like behavior. Then the patch changes device reset to LUN resets, and adds a target reset handler.
