*	nvmet: add support for the Write Zeroes command	Chaitanya Kulkarni	2016-12-01	1	-0/+29
\| \| \| \| \| \| \| \| \| \| \|	Add support for handling write zeroes command on target. Call into __blkdev_issue_zeroout, which the block layer expands into the best suitable variant of zeroing the LBAs. Allow write zeroes operation to deallocate the LBAs when calling __blkdev_issue_zeroout.

*	block: bio: pass bvec table to bio_init()	Ming Lei	2016-11-22	1	-3/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Some drivers often use external bvec table, so introduce this helper for this case. It is always safe to access the bio->bi_io_vec in this way for this case. After converting to this usage, it will becomes a bit easier to evaluate the remaining direct access to bio->bi_io_vec, so it can help to prepare for the following multipage bvec support.

*	block: move poll code to blk-mq	Jens Axboe	2016-11-11	1	-1/+1
\| \| \| \| \| \| \| \|	The poll code is blk-mq specific, let's move it to blk-mq.c. This is a prep patch for improving the polling code. Signed-off-by: Jens Axboe <axboe@fb.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
*	block,fs: use REQ_* flags directly	Christoph Hellwig	2016-11-01	1	-2/+2
\| \| \| \| \| \| \| \| \|	Remove the WRITE_* and READ_SYNC wrappers, and just use the flags directly. Where applicable this also drops usage of the bio_set_op_attrs wrapper. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@fb.com>

*	nvmet: Use direct IO for writes	Sagi Grimberg	2016-09-24	1	-0/+1
\| \| \| \| \| \| \| \| \| \|	We're designed to work with high-end devices where direct IO makes perfect sense. We noticed that we context switch by scheduling kblockd instead of going directly to the device without REQ_SYNC for writes.

*	nvmet: add a generic NVMe target	Christoph Hellwig	2016-07-05	1	-0/+215
	This patch introduces a implementation of NVMe subsystems, controllers and discovery service which allows to export NVMe namespaces across fabrics such as Ethernet, FC etc. The implementation conforms to the NVMe 1.2.1 specification and interoperates with NVMe over fabrics host implementations. Configuration works using configfs, and is best performed using the nvmetcli tool from http://git.infradead.org/users/hch/nvmetcli.git, which also has a detailed explanation of the required steps in the README file.
