So [patch 2/15] fixes all this up?

I guess we should join the two patches into one, to avoid a silly
breakage window.  That means that John loses a brownie point, but we
can mention him in the changelog, include his signed-off-by:

Several of these patches are missing your signed-off-by:.  They should
all have your SOB, because you sent them. 
Documentation/SubmittingPatches explains this.

I'm trying to find a way to merge all this code without reviewing it ;)
Alas, this is against my rules.  Given the length of time for which
this patchset has been floating around, I'm a little surprised by the
lack of acked-by's and reviewed-by's.  Have you been gathering them all
up?  Are the networking guys all happy about this patchset?
