*	block: move dif_prepare/dif_complete functions to block layer	Max Gurtovoy	2018-07-30	1	-0/+110
\| \| \| \| \| \| \| \| \| \| \| \| \|	Currently these functions are implemented in the scsi layer, but their actual place should be the block layer since T10-PI is a general data integrity feature that is used in the nvme protocol as well. Also, use the tuple size from the integrity profile since it may vary between integrity types. Suggested-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Martin K.

*	block: Dedicated error code fixups	Bart Van Assche	2017-06-16	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	This patch fixes two sparse warnings introduced by the "dedicated error codes for the block layer V3" patch series. These changes have not been tested.

*	block: switch bios to blk_status_t	Christoph Hellwig	2017-06-09	1	-15/+15
\| \| \| \| \| \| \| \| \| \|	Replace bi_error with a new bi_status to allow for a clear conversion. Note that device mapper overloaded bi_error with a private value, which we'll have to keep arround at least for now and thus propagate to a proper blk_status_t value.

*	block: constify struct blk_integrity_profile	Eric Biggers	2017-03-25	1	-4/+4
\| \| \| \| \| \| \| \|	blk_integrity_profile's are never modified, so mark them 'const' so that they are placed in .rodata and benefit from memory protection. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Jens Axboe <axboe@fb.com>
*	block: Consolidate static integrity profile properties	Martin K. Petersen	2015-10-21	1	-12/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	We previously made a complete copy of a device's data integrity profile even though several of the fields inside the blk_integrity struct are pointers to fixed template entries in t10-pi.c. Split the static and per-device portions so that we can reference the template directly. Signed-off-by: Martin K.

*	block: Add T10 Protection Information functions	Martin K. Petersen	2014-09-27	1	-0/+197
	The T10 Protection Information format is also used by some devices that do not go through the SCSI layer (virtual block devices, NVMe). Relocate the relevant functions to a block layer library that can be used without involving SCSI. Signed-off-by: Martin K.
