[PATCH 12/15] perf map: Combine maps__fixup_overlappings with its only use

From: Arnaldo Carvalho de Melo
Date: Tue Nov 12 2019 - 13:39:05 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

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.
