wait until some of the dependent topics graduate to 'master', and
rebase your work.
+ - Some parts of the system have dedicated maintainers with their own
+ repositories (see the section "Subsystems" below). Changes to
+ these parts should be based on their trees.
+
To find the tip of a topic branch, run "git log --first-parent
master..pu" and look for the merge commit. The second parent of this
commit is the tip of the topic branch.
You can also create your own tag or use one that's in common usage
such as "Thanks-to:", "Based-on-patch-by:", or "Mentored-by:".
