Hm, this conversation looks like a miscommunication, mainly? I see
Gustavo, as requested by many others[1], replacing the fallthrough
comments with the "fallthrough" statement. (This is more than just a
"Clang doesn't parse comments" issue.)

This could be a tree-wide patch and not bother you, but Greg KH has
generally advised us to send these changes broken out. Anyway, this
change still needs to land, so what would be the preferred path? I think
Gustavo could just carry it for Linus to merge without bothering you if
that'd be preferred?
