The best way to add the changelog requested by Greg's bot is to send a corrected v4 version. If you follow the example in https://docs.kernel.org/process/submitting-patches.html#the-canonical-patch-format then you'll see that what is expected. You can use git-notes to handle this. If you add a note containing something like the following: ~~~ Changes in v4: * Provide these changelogs. Changes in v3: * Changes in v2: * ~~~ Once you have the note than git-format-patch --notes will automatically included the changelog with the patch. Daniel. PS I know that v2 was circulated with an incorrect subject line but I think it is probably OK to call it v2 anyway... it makes the changelog clearer!
