Subject: [PATCH 04/15] perf tools: Add map_groups to 'struct addr_location'
Date: Tue, 12 Nov 2019 15:37:46 -0300	[thread overview]
Message-ID: <20191112183757.28660-5-acme@kernel.org> (raw)
In-Reply-To: <20191112183757.28660-1-acme@kernel.org>

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

From there we can get al->mg->machine, so replace that field with the
more useful 'struct map_groups' that for now we're obtaining from
al->map->groups, and that is one thing getting into the way of maps
being fully shareable.
