we just talk about oom-killer technical issues.
i am doubt that a new rewrite but the athor canot provide some evidence
and experiment result, why did you do that? what is the prominent change
for your new algorithm?
as KOSAKI Motohiro said, "you removed CAP_SYS_RESOURCE condition with
ZERO explanation".
David just said that pls use userspace tunable for protection by
oom_score_adj. but may i ask question:
1. what is your innovation for your new algorithm, the old one have the
same way for user tunable oom_adj.
2. if server like db-server/financial-server have huge import processes
(such as root/hardware access processes)want to be protection, you let
the administrator to find out which processes should be protection. you
will let the financial-server administrator huge crazy!! and lose so
many money!! ^~^
3. i see your email in LKML, you just said
"I have repeatedly said that the oom killer no longer kills KDE when run
on my desktop in the presence of a memory hogging task that was written
specifically to oom the machine."
http://thread.gmane.org/gmane.linux.kernel.mm/48998
so you just test your new oom_killer algorithm on your desktop with KDE,
so have you provide the detail how you do the test? is it do the
experiment again for anyone and got the same result as your comment ?
as KOSAKI Motohiro said, in reality word, it we makes 5-6 brain
simulation, embedded, desktop, web server,db server, hpc, finance.
Different workloads certenally makes big impact. have you do those
experiments?
i think that technology should base on experiment not on imagine.
Best,
