We were^W are still trying to make the shrinker nonblocking to avoid incurring horrible latencies for light direct reclaim. The consequence of avoiding heavy work in the shrinker is that we moved it to the oom notifier as being the last chance we have to return all (can be literally all) the system memory. The alternative to using a separate oom notifier would be more reclaim/shrinker phases? -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
