I've made required_fds a struct list_head list to accommodate for multiple fd:s (not sure that's absolutely needed though), so a couple of pointers need to be updated in sys_read/write. However, if that's too slow, and we only care about bookkeeping a single fd which is the case with sys_read/write, that can be changed into a single fd integer assignment.
Would that be fast enough?
