Subject: get_maintainers.pl: follow renames when looking up commit signers
X-Git-Tag: next-20111214~2^2~111
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=600f0d63df7af08cf96f0016114ea5913b9f77de;p=karo-tx-linux.git

get_maintainers.pl: follow renames when looking up commit signers

I happen to have had a commit to various network drivers since the big
renaming/reorg which happened to drivers/net recently.  This means that I
now appear to be in the top few commit signers (by %age) for many of them
so am getting sent all sorts of stuff and people who are involved with the
driver are not.  e.g.  (to pick one at random):

        $ ./scripts/get_maintainer.pl -f drivers/net/ethernet/nvidia/forcedeth.c
        "David S. Miller" <davem@davemloft.net> (commit_signer:5/7=71%)
        Ian Campbell <ian.campbell@citrix.com> (commit_signer:2/7=29%)
        Eric Dumazet <eric.dumazet@gmail.com> (commit_signer:1/7=14%)
        Jeff Kirsher <jeffrey.t.kirsher@intel.com> (commit_signer:1/7=14%)
        Jiri Pirko <jpirko@redhat.com> (commit_signer:1/7=14%)
        netdev@vger.kernel.org (open list:NETWORKING DRIVERS)
        linux-kernel@vger.kernel.org (open list)

With the following patch the renames are followed and the result appears
much more sensible:

        $ ./scripts/get_maintainer.pl -f drivers/net/ethernet/nvidia/forcedeth.c
        "David S. Miller" <davem@davemloft.net> (commit_signer:31/34=91%)
        Joe Perches <joe@perches.com> (commit_signer:11/34=32%)
        Szymon Janc <szymon@janc.net.pl> (commit_signer:5/34=15%)
        Jiri Pirko <jpirko@redhat.com> (commit_signer:3/34=9%)
        Paul <paul.gortmaker@windriver.com> (commit_signer:2/34=6%)
        netdev@vger.kernel.org (open list:NETWORKING DRIVERS)
        linux-kernel@vger.kernel.org (open list)
