You should use `git send-email` to send the patch to all of the people
listed by get_maintainer.pl:

richard@desktop ~/devel/linux $ scripts/get_maintainer.pl --file
drivers/scsi/scsi_transport_sas.c
"James E.J. Bottomley" <JBottomley@parallels.com> (maintainer:SCSI
SUBSYSTEM)
linux-scsi@vger.kernel.org (open list:SCSI SUBSYSTEM)
linux-kernel@vger.kernel.org (open list)

If I see that James E.J. Bottomley is already on CC for this discussion,
but my recent (and first) experience submitting a patch for another
subsystem was that they are ignored unless this strict procedure is
followed.

If the maintainer does not respond within a month after doing this, I
suggest informing Linus Torvalds via email that the subsystem maintainer
is non-responsive.
