Subject: [PATCH 12/15] perf map: Combine maps__fixup_overlappings with its only use
Date: Tue, 12 Nov 2019 15:37:54 -0300	[thread overview]
Message-ID: <20191112183757.28660-13-acme@kernel.org> (raw)
In-Reply-To: <20191112183757.28660-1-acme@kernel.org>

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

In the process we can kill some of the struct map->groups usage, trying
to get rid of this per-full struct map fields getting in the way of
sharing a map across father/parent processes.
