Kernel prepatch 5.12-rc6

The 5.12-rc6 kernel prepatch is out fortesting. "Well, if rc5 was bigger than usual, and I worried about what thatmeant for this release, rc6 is positively tiny.So I think it was just due to the usual random timing fluctuations,probably mainly networking updates (which were in rc5, but not inrc6). Which means that unless things change in the next two weeks, theschedule for this release is going to be the usual one."
