Hi Andrew,
the following two patches are on top of the current mmotm tree and the
first one is a fixup for 0eb77e988032 ("vmstat: make vmstat_updater
deferrable again and shut down on idle") merged during this merge
window. Mike has encountered issues [1] and the first patch fixes both
issues. The second patch is a follow up enhancement on top. I guess it
would be better to push this to 4.5 after it warms up in linux-next for
1-2 rc cycles to catch potential fallouts.
