That's a relief.  Please keep it this way - I plan on basing -mm on
linux-next after 2.6.26-rc1 and that should prevent reoccurrences.

That's nowhere as useful as it could be.

By keeping all this code out of -mm you haven't solved any of the
merge/integration problems which we had in 2.6.24-rcX.  They're all still
there.  All you did was to push them out of the two-month
integrate-and-test period and put them into the 2.6.25 merge window
instead.

whew.

No.  Was it ever sent out for review?

Would prefer to not have to go fishing in git trees to find code to review.
