Hi Eric (CC Eric and Marshall),

libc++ patches usually go to cfe-commits. I'm CCing Eric Fiselier and Marshall Clow, the primary libc++ maintainers.

libc++ patches usually go to cfe-commits.

Oh, I see that now. The list description sounded like it was only for commit
notifications from Subversion.

Thank you for helping me learn my way around.

cfe-commits is meant for both patches and commit notifications. The standard
procedure is to add cfe-commits as a subscriber when you're creating a libc++
patch using `arc diff`, which sends an email to the list.
