Kernel prepatch 5.12-rc7

The 5.12-rc7 kernel prepatch is out; it'srather larger than Linus would have liked."End result: I'm still waffling about the final 5.12 release. The factthat we have a big rc7 does make me think that I'll probably do an rc8this time around. But it ends up depending a bit on how the upcomingweek goes, and if things are deathly quiet, I may end up deciding thatan rc8 doesn't really make sense."
