I am planing to write a new device-mapper target and I'm wondering if there is a ordering guarantee for the operation inside a single bio? For example if I issue a write bio to sector 0 of length 4, is it guaranteed that sector 0 is written first and sector 3 is written last?
I'll bite. What are you doing where the order of writing out a single bio matters?
