Well, let's see what happens. If I rewind the tree to roughly
542181d3769d001c59cd17573dd4381e87d215f2 taking a wild guess at where my
tree was when I send the patch, and run it, here's what I get:
$ ./scripts/get_maintainer.pl 0001-ipc-initialize-structure-memory-to-zero-in-shm.patch
Al Viro <viro@zeniv.linux.org.uk>
Andrew Morton <akpm@linux-foundation.org>
Jiri Slaby <jslaby@suse.cz>
"Serge E. Hallyn" <serue@us.ibm.com>
"David S. Miller" <davem@davemloft.net>
linux-kernel@vger.kernel.org
And since I know Serge's address isn't at ibm any more, I dropped it from
Cc, assuming he didn't care about ipc structure fixups.
If I fast-forward to today and run it, I get the same output you do.
