The mmap_sem is a big scalability bottleneck and there are several projects for solving it. In this mail, Matthew Wilcox suggests his plan for his solution and asks whether a exceptional case in his solution is acceptable to other people.

Linux 5.5 merge window closed and the -rc1 has released. It was a tiny bit larger release compared to recent several releases, but fairly regular overall. perf and kselftest was a standout, but Torvalds says it is normal in these days.

My favorite new feature in 5.5-rc1 is kunit. Now you can do unit test of the kernel in very fast and convenient way!
