From 230934a6fe2f44d14ef840639f010c9cf4da098f Mon Sep 17 00:00:00 2001 From: Brian King Date: Mon, 19 Oct 2009 15:07:47 -0500 Subject: [SCSI] ibmvfc: Fixup TMF response handling When processing the response to either a LUN reset, target reset, or an abort task set, the ibmvfc driver needs to treat as success receiving a response with a non-zero status in the response IU along with a general transport error with the FCP response code being zero. The VIOS currently guarantees this cannot happen, but a future version of VIOS may allow this to be returned, so ensure we handle this response combination correctly for TMFs, as we already do for SCSI commands.
