From df4bf0bb5b077545031e8ad5ef3cc0dd8a5fbe05 Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Thu, 31 Jan 2008 12:33:46 -0800 Subject: [SCSI] qla2xxx: Cleanup any outstanding SRB resources during shutdown. Refactor SRB-failure completion codes in the process. Also, signal the DPC routine to complete sooner as backend processing at shutdown-time is superflous.
