Thanks for respining this. A few words about the patch submission
process though:
- Please add a version number (v2, v3...) to your patch series. It helps
the reviewers keeping track of where we are in the review process
- Add a change log to your cover letter. Clearly state what
changed. Otherwise, reviewers have to start diffing between patches,
which becomes quickly messy, specially considering the lack of
versioning.
- Make sure your patches are part of an email thread starting with your
cover letter. This helps reviewers to locate the various patches in a
busy Inbox, and to follow the evolution of a discussion. Use of "git
send-email" is recommended for posting the patch series.
That being said, I'm off to review the actual patches... ;-)
Thanks,
M.
