General 2.4 impressions (was Re: [PATCH] Prevent OOM from killing init)

[Jeff Garzik]

Personally I think the OOM killer itself is fine.  I think there are
problems elsewhere which are triggering the OOM killer when it should
not be triggered, ie. a leak like Doug Ledford was reporting.

I definitely see heavier page/dcache usage in 2.4 -- but that is to be
expected due to 2.4 changes!  So it is incredibily difficult to quantify
if something is wrong, and if so, where...

My own impressions of 2.4 are that it "feels faster" for my own uses and
it's stable.  The downsides I find are that heavy fs activity seems to
imply increased swapping, which jibes with a guess that the page/dcache
is exceptionally greedy with releasing pages under memory pressure.
