In that case it might be better when pushed separately, just to avoid
any chances on a merge conflict for the bkl/vfs tree. I was thinking of
letting the initial merges hit, rebase and retest over the weekend if
there were any Coda related changes, and sending the final version to
Linus by monday.

Besides, that gives me a couple of more days to make sure I weed out any
remaining issues.
