+Patch Conflict Resolution

-If a change has a conflict it should be resolved by entering:
+Two different patch conflict scenarios arise from time to
+time. Sometime after uploading a patch to https://gerrit.fd.io, the
+gerrit UI may show a patch status of "Merge Conflict."
+
+Or, you may attempt to upload a new patch-set via "git review," only to
+discover that the gerrit server won't allow the upload due to an upstream
+merge conflict.
+
+In both cases, it's [usually] fairly simple to fix the problem. You
+need to rebase the patch onto master/latest. Details vary from case to
+case.
+
+Here's how to rebase a patch previously uploaded to the Gerrit server
+which now has a merge conflict. In a fresh workspace cloned from
