Subject: [PATCH 03/17] tools headers: Grab copy of linux/const.h, needed by linux/bits.h
Date: Tue, 20 Aug 2019 16:27:19 -0300	[thread overview]
Message-ID: <20190820192733.19180-4-acme@kernel.org> (raw)
In-Reply-To: <20190820192733.19180-1-acme@kernel.org>

From: Arnaldo Carvalho de Melo <acme@redhat.com>

So that can update the copy of linux/bits.h that now uses macros defined
in const.h and that are not available in older systems.
