From 0c23b856581673c90aa619b1ab04127a7f90cea2 Mon Sep 17 00:00:00 2001 From: Andrew Vasquez Date: Thu, 24 Apr 2008 15:21:25 -0700 Subject: [PATCH] [SCSI] qla2xxx: Correct SRB usage-after-completion/free issues. The driver is incorrectly assuming that the 'sp' reference held in qla2[x00|4xx]_abort_command() is valid after the mailbox command is issued to abort the exchange. It is *not*, as the command may be completed during interrupt context before control is returned to the mailbox caller.
