This series makes REQ_OP_WRITE_ZEROES the only zeroing offload
supported by the block layer, and switches existing implementations
of REQ_OP_DISCARD that correctly set discard_zeroes_data to it,
removes incorrect discard_zeroes_data, and also switches WRITE SAME
based zeroing in SCSI to this new method.
The series is against the block for-next tree.
A git tree is also avaiable at:
Changes since V2:
- various spelling fixes
- various reviews captured
- two new patches from Martin at the end
