[PATCH 3.8 071/166] firewire: sbp2: bring back WRITE SAME support

From: Kamal Mostafa
Date: Wed Jan 15 2014 - 17:01:29 EST


3.8.13.16 -stable review patch. If anyone has any objections, please let me know.

------------------

From: Stefan Richter <stefanr@xxxxxxxxxxxxxxxxx>

commit ce027ed98fd176710fb14be9d6015697b62436f0 upstream.

Commit 54b2b50c20a6 "[SCSI] Disable WRITE SAME for RAID and virtual
host adapter drivers" disabled WRITE SAME support for all SBP-2 attached
targets. But as described in the changelog of commit b0ea5f19d3d8
"firewire: sbp2: allow WRITE SAME and REPORT SUPPORTED OPERATION CODES",
it is not required to blacklist WRITE SAME.

Bring the feature back by reverting the sbp2.c hunk of commit 54b2b50c20a6.
