[PATCH 18/52] perf map: Shorten map_groups__find_by_name() signature

From: Arnaldo Carvalho de Melo
Date: Wed May 02 2018 - 11:30:49 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Another step in the road to elliminate the MAP_{FUNCTION,VARIABLE}
separation, reducing the exposure to these details in the tools using
the symbol APIs.
