Yeah, the VLA patches have been going through maintainer trees --
mostly due to needing specialized review, etc. While many are trivial,
a fair number aren't (or at least the trade-offs aren't always
obvious).

Yeah, I'm in no rush to collect the "unresponded" VLA patches into a
tree, and we've still got more to go, so right now it'd just be a
single-patch pull. If you can snag it now, that'd be great! :)
