Subject: [PATCH] get_maintainer.pl: append reason for cc to the name by default
The script get_maintainer.pl is a very useful tool for deploying changes
made to the kernel. Among others it searches not only the MAINTAINERS
file but also the git history for people to send patches to.
This can be unexpected for the receiving side and can and does provoke
sometimes anger because it is not easy to determine if the sender did
explicitly put the receiving side on the cc list, or if they just
trolled the tree. The receiving side, if not used to be cc'd on many
things will check the patch, spend time investigating what the heck they
were cc'd just to realize, that there was no special reason.
As get_maintainer.pl is frequently used by kernel newcommers who _can_
not know whom to cc by themself, this anger then comes as a surprise for them
and definitely puts them in an awkward position.
By appending a a note of the reason for the cc in the name, the reason
becomes clear and the receiving side is relieved from feeling obliged to
check the patch while the sending side has a chance to adapt the
cc'list to their liking.
But the most useful aspect of this is, IMHO, that it makes it transparent who
just used get_maintainer.pl as a shortcut to increase his own
patch-throughput or who really put an effort in finding or editing the
cc'list to their likings.
