When you post a new version of a patch or a patch series, could you do
the following:

- add v2 or v3, or ... after "PATCH" in the subject, so that we know
which version it is (see the mailing list archive and the format-patch
documentation to see how it should appear and how to do it)
- tell what you changed since the previous version, and maybe also why
you made those changes, if it has not already been explained or
discussed (you can do it after the "---" above and before the file
stats below, or in a separate email replying to the patch, or in the
cover letter of the patch series if you are sending a patch series)

I think it would be better if the 'head' commands above and the 'grep'
command below were also on their own line.
