Hello, I am debugging Filesystem code for USB mass storage devices. I need help to figure out after generic_make_request how the request is placed to scsi disk (sd) requeset queue and than how sd qeueuecommand to usb_storeage thread. (in which context, is it system call context) inside generic_make_request 1. q = bdev_get_queue(bio->bi_bdev); [is sd.c register queue this queue or any other scsi file?] 2. ret = q->make_request_fn(q, bio); [which file contain this make_request_fn for scsi disk driver (generic)] As per my unsderanding flow is like Fat_writepage ->_block_write_full_page --> blkdev_writepage--> block_write_full_page-->submit_bh-->generic_make_request ??? (sd ??) ----> queuecommand Please suggest any sorce file, link or document. with thanks Ravish -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
