Subject: [PATCH 01/15] perf map: Use map->dso->kernel + map__kmaps() in map__kmaps()
Date: Tue, 12 Nov 2019 15:37:43 -0300	[thread overview]
Message-ID: <20191112183757.28660-2-acme@kernel.org> (raw)
In-Reply-To: <20191112183757.28660-1-acme@kernel.org>

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

Its equivalent to using map->groups to obtain the machine struct.
