Good day all, is there a way to batch explicitely write requests raid5 issues? for example, there is a raid5 built from 3 disks with chunk=64K. one types dd if=/dev/zero of=/dev/md0 bs=128k count=1 and 128K bio gets into the raid5. raid5 processes the request, does xor for parity stripe, then issues 2 64KB requests down to lower level. is it even possible to implement? if so, how complex? I suppose we could introduce a context which holds last non-issued bio and instead of generic_make_request() in handle_stripe() try to merge current request to the previous one from the context? how does this sound to you? thanks, Alex - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
