Now that we are using REQ_OP_WRITE_ZEROES for all zeroing needs in the
kernel there is very little use left for REQ_OP_WRITE_SAME.  We only
have two callers left, and both just export optional protocol features
to remote systems: DRBD and the target code.

No particular objections from me. I had a half-baked series to do the
same thing.

One thing I would like is to either pull this series through SCSI or do
the block pieces in a post merge branch because I'm about to post my
discard/zeroing rework and that's going to clash with your changes.

I'd be fine with taking this through the SCSI tree.  Or we can wait
another merge window to make your life easier.
