All reviewed patches have been landed. Closing bug.
<rdar://problem/56806865>
Reverted in r251967 together with r251875, because this patch was conflicting with the rollback. Sorry for the inconvenience.
I'm not sure if this was a fix after r251875, or a fix of its own (didn't look at the code). Please close or re-land as appropriate.
It is already landed.
