 If the patch is already upstream, and the upstream patch applies cleanly,
please use the upstream patch instead (adding you Sob if necessary and adding a
reference to the upstream commit sha). If the upstream patch does not apply
cleanly you can keep using this custom patch, but please still add a reference
to the upstream sha.
