When you write release notes for this series, you may want to consider
also calling out one or more of the bugs that were fixed as a side
  * a bug causing dirty files involved in a rename to be overwritten
during merge
  * a few memory leaks
I added a reminder about these two fixes in the cover letter for my
latest (and possibly last?) roll of the series that I just sent out.
