I dunno, the interface just seems goofy to me.

Yes, it's always been strange that rlimits cannot be externally
altered.  And desirable to extend that.  But doing what is really a
syscall via a profs poke when there already exists a syscall which does
the same thing seems Just Wrong.

What reason is there to do it via procfs?  Where's the benefit?

Maybe it's a plot to stop people from setting CONFIG_PROC_FS=n.
