blkdev_issue_zeroout - generate number of zero filed write bios : blockdev to issue : start sector : number of sectors to write : memory allocation flags (for bio_alloc)
Description: Generate and issue number of bios with zerofiled pages.
Definition at line 217 of file blk-lib.c.
blkdev_issue_discard - queue a discard : blockdev to issue discard for : start sector : number of sectors to discard : memory allocation flags (for bio_alloc) : BLKDEV_IFL_* flags to control behaviour
Description: Issue a discard request for the sectors in question.
