名称描述
bio_uninit
bio_clone_fast_clone_fast - clone a bio that shares the original bio's biovec*@bio: bio to clone*@gfp_mask: allocation priority*@bs: bio_set to allocate from* Like __bio_clone_fast, only also allocates the returned bio
bio_advance_advance - increment/complete a bio by some number of bytes*@bio: bio to advance*@bytes: number of bytes to complete* This updates bi_sector, bi_size and bi_idx; if the number of bytes to* complete doesn't align with a bvec boundary, then bv_len and
bio_split_split - split a bio*@bio: bio to split*@sectors: number of sectors to split from the front of @bio*@gfp: gfp mask*@bs: bio set to allocate from* Allocates and returns a new bio which represents @sectors from the start of
bio_trim_trim - trim a bio*@bio: bio to trim*@offset: number of sectors to trim from the front of @bio*@size: size we want to trim @bio to, in sectors
bounce_clone_bio
bio_integrity_free_integrity_free - Free bio integrity payload*@bio: bio containing bip to be freed* Description: Used to free the integrity portion of a bio. Usually* called from bio_free().
bio_integrity_add_page_integrity_add_page - Attach integrity metadata*@bio: bio to update*@page: page containing integrity metadata*@len: number of bytes of integrity metadata in page*@offset: start offset within page
bio_integrity_process_integrity_process - Process integrity metadata for a bio*@bio: bio to generate/verify integrity metadata for*@proc_iter: iterator to process*@proc_fn: Pointer to the relevant processing function
bio_integrity_prep_integrity_prep - Prepare bio for integrity I/O*@bio: bio to prepare* Description: Checks if the bio already has an integrity payload attached.* If it does, the payload has been generated by another kernel subsystem,* and we just pass it through
__bio_integrity_endio__bio_integrity_endio - Integrity I/O completion function*@bio: Protected bio* Description: Completion for integrity I/O* Normally I/O completion is done in interrupt context. However,* verifying I/O integrity is a time-consuming task which must be run
bio_integrity_advance_integrity_advance - Advance integrity vector*@bio: bio whose integrity vector to update*@bytes_done: number of data bytes that have been completed* Description: This function calculates how many integrity bytes the* number of completed data bytes
bio_integrity_trim_integrity_trim - Trim integrity vector*@bio: bio whose integrity vector to update* Description: Used to trim the integrity vector in a cloned bio.
bio_integrity_clone_integrity_clone - Callback for cloning bios with integrity metadata*@bio: New bio*@bio_src: Original bio*@gfp_mask: Memory allocation mask* Description: Called to allocate a bip when cloning a bio
blk_integrity_merge_rq
blk_integrity_merge_bio
t10_pi_type1_prepare10_pi_type1_prepare - prepare PI prior submitting request to device*@rq: request with PI that should be prepared* For Type 1/Type 2, the virtual start sector is the one that was* originally submitted by the block layer for the ref_tag usage. Due to
t10_pi_type1_complete10_pi_type1_complete - prepare PI prior returning request to the blk layer*@rq: request with PI that should be prepared*@nr_bytes: total bytes to prepare* For Type 1/Type 2, the virtual start sector is the one that was
