Do you mean "fields"? yes i mean fields, my bad. >This sounds like stuff you do in the driver , on receipt of your special >request. Is that so and how do you recognize it by checking the MAJOR and MINOR num of my disk !!!!! ? >Default interrupt handler? remember i said , i set a different intr. handler if its my disk !? well, after its handled there, i dont call end_request , simple. eg. mult_write is the default intr. handler for multiple writes ? i set mult_write_withoutend as the handler, then after the handling is done , i again set mult_write as the handler.... this will call the end_request. >or whether you only have one request hit the >driver and when it hits you simply treat it twice bingo ! >Probably because some stuff is returned to kernel pools and messes them >up completely. what stuff ? im not returning anything to any queue whatsoever ! >Because your code, like your description, is an uncontrolled mess, >probably. about the code .. umm , maybe not , coz the write is duplicated alright .. my description , a mess ?... nope , what im doing is really simple , as i stated in the very first mail , im doing something similar to RAID 1 !! , what s so hard to understand in that ? I also said , why im continuing with the IDE modifications inspite of the RAID 1 drivers. --snipped-- However, in my driver (modified IDE) I have to take care of the writes and reads individualy. The advantage here is that, i dont need to make 4 partitions of the disk, one is good enough, and the remaining can be unallocated. I make the write at fixed offsets into the unallocated space, and when read is requested, I read em one by one, and check. --snipped-- So now ( after im done with the read requests ) i have two options for them... RAID 1 and the modified the IDE driver.
