The ideas that have been floated around in this thread barely cross into nice-to-have territory, and as a result the acceptable additional complexity to implement them is very low as well. Making the OOM behavior less consistent, or introducing very rare problem behavior (e.g. merely reducing the probability of syscalls returning -ENOMEM instead of fully eliminating it, re-adding avenues for deadlocks, no matter how rare, etc.) is a non-starter. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
