Subject: [PATCH] Make retries obey host_self_blocked flag #2
Date: Thu, 05 Feb 2004 16:49:48 -0600 [thread overview]
Message-ID: <4022C88C.3000804@us.ibm.com> (raw)

Lets try this again, this time with the patch attached....
The following patch against 2.6.2 will prevent the midlayer from
issuing retries if host_self_blocked is set. This was raised as an
issue here:
http://marc.theaimsgroup.com/?l=linux-scsi&m=107357742430401&w=2
I'm trying to improve and extend scsi_block_requests, and this is
the first, and hopefully least controversial, step.
