These new headers are added after the "From: " line in the patch. Currently, for a single patch, maintainers and reviewers are added as "To: ", mailing lists and all other roles are added as "Cc: ". For a series of patches, however, a set-union scheme is employed in order to solve the all-too-common problem of ending up sending only subsets of a patch series to some lists, which results in important pieces of context such as the cover letter (or other patches in the series) being dropped from those lists. This scheme is as follows: - Create set-union of all maintainers and reviewers from all patches and use this to do the following per patch: - add only that specific patch's maintainers and reviewers as "To: " - add the other maintainers and reviewers from the other patches as "Cc: " - Create set-union of all mailing lists corresponding to all patches and add this to all patches as "Cc: " - Create set-union of all other roles corresponding to all patches and add this to all patches as "Cc: " Please note that patch files that don't have any "Maintainer"s or "Reviewers" explicitly listed in their `get_maintainer.pl` output will not have any "To: " entries added to them; developers are expected to manually make edits to the added entries in such cases to convert some "Cc: " entries to "To: " as desired. The script is quiet by default (only prints errors) and its verbosity can be adjusted via an optional parameter.
