Can we leave the non-oom related parts of procfs as-is for now, then
migrate them over to hpcc when that is available? Safer that way.
Of course.
So AFAIU the plan is:
1) update the oom accuracy fix to only use the precise sum for
the oom killer, no changes to procfs ABIs. This targets mm-new.
2) update the hpcc series to base them on top of the new fix from (1).
Update their commit messages to indicate that they bring accuracy
improvements to the procfs ABI on large many-core systems, as well as
latency improvements to the oom killer. This will target upstreaming
after the next merge window, but I will still post it soon to gather
feedback.
Does that plan look OK ?
Thanks,
Mathieu
