Yeah, actually I feel the same. The merge window is going to open on Sunday
and the series isn't still fully baked and happily sitting in linux-next
(and larger changes should really sit in linux-next for at least a week,
preferably two, before the merge window opens to get some reasonable test
coverage).  So I'd take out the independent easy patches that are already
reviewed, get them merged into Andrew's (or whatever other appropriate
tree) now so that they get at least a week of testing in linux-next before
going upstream.  And the more involved bits will have to wait for 5.6 -
which means let's just continue working on them as we do now because
ideally in 4 weeks we should have them ready with all the reviews so that
they can be picked up and integrated into linux-next.
