Hi All, I want to write a layered driver for a device in Linux. I am overwriting make_request_fn in blk_dev strucure. Whenever they is an I/O my make_request_fn is called so that I can change the buffer_head and send to other disk by calling submit_bh in my make_request_fn as following. bh->b_dev = MKDEV(252,0); // I am changing to other disk device atomic_set(&bh->b_count, 1); submit_bh(WRITE, bh); This is not working. It is giving me kernel panic Could you help me how should I go about it? My purpose is all I/O to Disk1 should to passed to Disk2.
