Subject: always use REQ_OP_WRITE_ZEROES for zeroing offload V2
Date: Wed, 5 Apr 2017 16:21:38 +0200 [thread overview]
Message-ID: <20170405142205.6477-1-hch@lst.de> (raw)
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:
git://git.infradead.org/users/hch/block.git discard-rework.2
Gitweb:
http://git.infradead.org/users/hch/block.git/shortlog/refs/heads/discard-rework.2
Changes since V2:
- various spelling fixes
- various reviews captured
- two new patches from Martin at the end
