Subject: [PATCH 28/34] perf symbols: Constify dso->long_name
From: Arnaldo Carvalho de Melo <acme@...hat.com>
Same reason as for dso->short_name, it may point to a const string, and
in most places it is treated as const, i.e. it is just accessed for
using its contents as a key or to show it on reports.
