Hi, all
Since there is a practical needs for user application with the ability
to sense kernel memory use pressure,
http://elinux.org/Memory_Management gives some approach on this as below:
OOM notification in cgroups
mem_notify patches
Google cgroup OOM handler
Nokia OOM enhancements
OOM by itself is for non-critical server, or hand-held devices where physical memory is severely constrained. For server running database, or any high end server, it is disastrous to have it turned on. Judge for yourself the criticality of your applications and turn it on/off if needs to:
For the latest development, read this:
and the Documentation/feature-removal-schedule.txt and Documentation/cgroups/memory.txt
has some development on OOM as well
AFAIK, it seems none of these have been merged into mainline or updated
continuously,
I'm not so familiar with mm system, so may I ask which known approach is
best to work with mainline kernel now?
