Hi Mike,
I re-test it in v5.9-rc8, the regression still existed. It is almost
the same as 34ae204f1851. Do you have time to look at it? Thanks.

Would you be willing to test this series on top of 34ae204f1851? I will need
to rebase the series to take the changes made by 34ae204f1851 into account.
Actually, the series in this thread will apply/run cleanly on top of
34ae204f1851. No need to rebase or port. If we decide to move forward more
work is required. See a few FIXME's in the patches.
