When multiple partitions are used, you may want to enforce different subsets of the available write hints for each partition. Provide a bitmap attribute of the available write hints, and allow an admin to write a different mask to set the partition's allowed write hints.
After /proc/irq/*/smp_affinity was introduced (a bitmask), /proc/irq/*/smp_affinity_list (set of ranges) was introduced as a more user-friendly alternative. Is the same expected to happen with the write_hint_mask? If so, shouldn't we skip the bitmask user space interface and directly introduce the more user friendly interface (set of ranges)? Thanks, Bart.
