名称	描述
submit_bio	submit_bio - submit a bio to the block device layer for I/O@bio: The &struct bio which describes the I/O submit_bio() is very similar in purpose to generic_make_request(), and* uses that function to do most of the work. Both are fairly rough
queue_logical_block_size_show
get_max_io_size	Return the maximum number of sectors from the start of a bio that may be* submitted as a single request to a block device. If enough sectors remain,* align the end to the physical block size. Otherwise align the end to the* logical block size
blk_integrity_register	lk_integrity_register - Register a gendisk as being integrity-capable@disk: struct gendisk pointer to make integrity-aware@template: block integrity profile to register* Description: When a device needs to advertise itself as being able to* send/receive
bdev_logical_block_size
bio_allowed_max_sectors	The max size one bio can handle is UINT_MAX becasue bvec_iter.bi_size* is defined as 'unsigned int', meantime it has to aligned to with logical* block size which is the minimum accepted unit by hardware.
