I have a question about block layer in 2.4 kernel. I'm printing info about block devices and noticed
There are not request_fn and make_request_fn for major numbers 8 and 3(scsi and ide) Parameter head_active == 0 for both. But do_hd_request and scci_request_fn do get called of course. The flow for read/write is: Block_read->ll_rw_block->submit_bh->generic_make_request->make_request_fn->__make_request .. Default make_request_fn is __make_request which is called by blk_init_queue. Do I understand right the picture ? Why make_request_fn == 0 for ide and scsi? Actually only floppy device has both function != 0. ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
