linux-5.5 mm looks very good

My tests with the upcoming Linux kernel are looking very promising. For me memory management issue has been improved a lot. In recent 5.x kernels the mm would trigger a lot of reclaim scans even with low memory pressure. For example  on a 2GB laptop the Normal zone is quite small. Most memory is in the DMA32 zone. And those kernels would trigger reclaim and even swap when opening a browser or using gitk on the kernel repo. Even though there is still plenty of usable RAM.
With 5.5 this is resolved. Reclaim scans are rare again and swap is not used in these situations.
