Hi, Oleg, Oleg Nesterov <oleg@xxxxxxxxxx> writes: > Shouldn't we account aio events/pages somehow, say per-user, or in > mm->pinned_vm ? Ages ago I wrote a patch to account the completion ring to a process' memlock limit: "[patch] aio: remove aio-max-nr and instead use the memlock rlimit to limit the number of pages pinned for the aio completion ring" http://marc.info/?l=linux-aio&m=123661380807041&w=2 The problem with that patch is that it modifies the user/kernel interface. It could be done over time, as Andrew outlined in that thread, but I've been reluctant to take that on. If you just mean we should account the memory so that the right process can be killed, that sounds like a good idea to me.
