This really looks like it should come in the next merge window, not during rc7.

You had absolutely zero csky updates during the merge window, you
can't then magically come up with "look, here's 1300 lines of fixes"
during the late rc series.

Re-send when the merge window opens.

You are right and I know I've missed 5.1-rc1 merge window.
