Sure, no problem. Do you have an opinion on the question I raised in the first patch [1], i.e. whether we actually want this to be done this way in the kernel, or one of the other approaches I described there?
So this looks like the most forward looking variant:
a) deprecate the wait4() and getrusage() system calls, and create a set of kernel interfaces based around a newly defined structure that could solve multiple problems at once, e.g. provide more fine-grained timestamps. The C library could then implement the posix interfaces on top of the new system calls.
... but given the pretty long propagation time of new ABIs, is this a good solution? What would the limitations/trade-offs be on old-ABI systems?
Thanks,
