Hi, I have a SATA disk which is represented by node /dev/sdb. I opened that device using open_blk_excl() to perform IO from a kernel module. IO request is submitted using generic_make_request() which is in terms of struct bio. As per my knowledge LLDs do not deal with struct bio. My question is, where does the struct bio to struct scatterlist conversion takes place before SCSI layer calls hostt->queuecommand()?
