On http://releases.llvm.org/7.0.0/docs/LangRef.html#difile, it still reads "Valid values for checksumkind: field are: {CSK_None, CSK_MD5, CSK_SHA1}" even though CSK_None is now invalid (clang would print "error: invalid checksum kind 'CSK_None'").
The checksumkind parameter should be marked optional in the docs, and the CSK_None should be removed.
