Subject: [git pull] FireWire fixlet


please pull from the tag "firewire-fix" at

    git:// firewire-fix

to receive a one-liner fix/ revert.  This reenables WRITE SAME over SBP-2
like in v3.8...v3.12 (or v3.8-rc1...v3.13-rc2 to be overly precise).
Buggy targets which could malfunction when being subjected to this command
are already sufficiently protected by a scsi_level check in sd + SCSI core.

Subject: [PATCH] firewire: sbp2: bring back WRITE SAME support

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
it is not required to blacklist WRITE SAME.

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