There's a tool, scripts/get_maintainer.pl, that can tell you who you ask about who is responsible for various bits of the kernel. $ ./scripts/get_maintainer.pl -f drivers/usb/serial/ch341.c Johan Hovold <johan@kernel.org> (maintainer:USB SERIAL SUBSYSTEM) Greg Kroah-Hartman <gregkh@linuxfoundation.org> (supporter:USB SUBSYSTEM) linux-usb@vger.kernel.org (open list:USB SERIAL SUBSYSTEM) linux-kernel@vger.kernel.org (open list)
