Re: [PATCH] init_task: Include <linux/rbtree.h> in the right file

[Marco Elver <elver@google.com>]

[+Cc Ingo, who had been working on lots of include improvements.]

The Cc list is odd -- it appears that get_maintainers.pl is broken on
init_task.c:

	$> ./scripts/get_maintainer.pl init/init_task.c
	Mark Rutland <mark.rutland@arm.com> (commit_signer:1/1=100%)
	"Paul E. McKenney" <paulmck@kernel.org> (commit_signer:1/1=100%)
	Marco Elver <elver@google.com> (commit_signer:1/1=100%,authored:1/1=100%,removed_lines:5/5=100%)
	linux-kernel@vger.kernel.org (open list)

What's going on here?
