Given that 99.99% of programs don't appear to care and you materially
slow down a critical path for every read and write I'm skeptical.
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?
