Linus has released 5.8-rc1 and closed the
merge window for this release. By the end, 14,206 non-merge changesets
found their way into the mainline repository, making this one of the
busiest development cycles ever. “So in the 5.8 merge window we have modified about 20% of all the files
in the kernel source repository. That’s really a fairly big
percentage, and while some of it _is_ scripted, on the whole it’s
really just the same pattern: 5.8 has simply seen a lot of
development.

IOW, 5.8 looks big. Really big.“
