Hi Joe,

I haven't looked closely at scripts/get_maintainer.pl, but I recently 
wrote a patch touching mm/vmpressure.c and it doesn't list the file's 
author, Anton Vorontsov <anton.vorontsov@linaro.org>.

Even when I do scripts/get_maintainer.pl -f mm/vmpressure.c, his entry is 
missing and git blame attributs >90% of the lines to his authorship.

$ ./scripts/get_maintainer.pl -f mm/vmpressure.c

Any ideas?
