When submitting a new version of a previously submitted patch, you should do a few additional things:
Uniquely identify the new version. You can usegit format-patch -vN, incrementing N each time; or you can add an incrementing numerical suffix manually. Using the ".patch" extension allows some reviewers to more easily read it in their email client/code editor.
Make sure it's easy to find any earlier discussion of the patch, by providingMessage-Id-based links to themailing list posts. Don't expect that everyone will still be able to find previous submissions on their own. You can usually get the message ID of your email by looking for the headerMessage-Idin your email client. TryView message sourceorView originalif it's not obviously visible.
