I'm not sure how you reach that conclusion: it's necessary because any process handling the oom condition will need memory to do anything useful. How else would a process that is handling a system oom condition, for example, be able to obtain a list of processes, check memory usage, issue a kill, do any logging, collect heap or smaps samples, or signal processes to throttle incoming requests without having access to memory itself? The system is oom. > Just changing a part of it and > resubmitting doesn't really change the whole situation.

I feel no need to refer to an older patchset that would not apply and did not include all the support necessary for handling oom conditions. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
