Kernel prepatch 5.13-rc3
The third 5.13 kernel prepatch is out for
testing. "It's been a very calm rc3 week, and at least in pure
number of commits this is the smallest rc3 we've had in the 5.x
series.

Considering that the merge window was not in any way small, this is a
bit surprising, but I suspect it's one of those 'not everybody sent in
fixes this week' things that will rectify itself next week."
This prepatch does include reverts and fixes for a long series of broken
patches identified in the TAB report on the UMN
mess.
