Looks good! Thank you!

Do you need me to submit the patch for you?

[mgehre]

Yes, please. Btw, I'm going to submit some diffs for clang-tidy checks (for
the CppCoreGuidelines). Which reviewers should I set on them?

Please always add me to the reviewers and cfe-commits to Subscribers. Also note, that in October I'll be mostly unavailable, but other clang-tidy contributors can do the review and help getting patches in: sbenza, bkramer, aaron.ballman.

Patches are always welcome ;)
