Kernel prepatch 5.8-rc1

Linus has released 5.8-rc1 and closed themerge window for this release. By the end, 14,206 non-merge changesetsfound their way into the mainline repository, making this one of thebusiest development cycles ever. "So in the 5.8 merge window we have modified about 20% of all the filesin the kernel source repository. That's really a fairly bigpercentage, and while some of it _is_ scripted, on the whole it'sreally just the same pattern: 5.8 has simply seen a lot ofdevelopment.IOW, 5.8 looks big. Really big."
