bio-integrity: update the payload size in bio_integrity_add_page()

2023-08-09T22:05:35Z

Previously, the bip's bi_size has been set before an integrity pages were added. If a problem occurs in the process of adding pages for bip, the bi_size mismatch problem must be dealt with. When the page is successfully added to bvec, the bi_size is updated. The parts affected by the change were also contained in this commit. Cc: Christoph Hellwig Cc: Martin K.

block: replace fmode_t with a block-specific type for block open flags

2023-06-12T14:04:05Z

The only overlap between the block open flags mapped into the fmode_t and other uses of fmode_t are FMODE_READ and FMODE_WRITE. Define a new blk_mode_t instead for use in blkdev_get_by_{dev,path}, ->open and ->ioctl and stop abusing fmode_t.

block: use the holder as indication for exclusive opens

2023-06-12T14:04:04Z

The current interface for exclusive opens is rather confusing as it requires both the FMODE_EXCL flag and a holder. Remove the need to pass FMODE_EXCL and just key off the exclusive open off a non-NULL holder. For blkdev_put this requires adding the holder argument, which provides better debug checking that only the holder actually releases the hold, but at the same time allows removing the now superfluous mode argument.

block: introduce holder ops

2023-06-05T16:53:04Z

Add a new blk_holder_ops structure, which is passed to blkdev_get_by_* and installed in the block_device for exclusive claims. It will be used to allow the block layer to call back into the user of the block device for thing like notification of a removed device or a device resize.

nvmet: don't look at the request_queue in nvmet_bdev_set_limits

2022-09-27T16:51:50Z

nvmet is a consumer of the block layer and should not directly look at the request_queue. Use the bdev_ helpers to retrieve the device limits instead. Signed-off-by: Christoph Hellwig Reviewed-by: Keith Busch

nvmet: avoid unnecessary flush bio

For no volatile write cache block device backend, sending flush bio is unnecessary, avoid to do that. Signed-off-by: Guixin Liu Reviewed-by: Chaitanya Kulkarni Signed-off-by: Christoph Hellwig

nvme/target: Use the new blk_opf_t type

2022-07-14T18:14:32Z

Improve static type checking by using the new blk_opf_t type for variables that represent a request operation combined with request flags. Rename those variables from 'op' into 'opf'.

block: decouple REQ_OP_SECURE_ERASE from REQ_OP_DISCARD

2022-04-18T01:49:59Z

Secure erase is a very different operation from discard in that it is a data integrity operation vs hint. Fully split the limits and helper infrastructure to make the separation more clear.
