Make essentials survive the OOM-killer asked for disabling OOM killer for some “essentials”, which were concluded to not be essentials in all cases. But btrfs? I hope there’s no discussion that OOM killer should be disabled for that one. This might explain my neverending problems with btrfs - every now and then I see some btrfs errors in kernel log, even though scrub doesn’t find anything wrong.
