From: Arnaldo Carvalho de Melo Date: Tue, 10 Dec 2013 18:08:44 +0000 (-0300) Subject: perf symbols: Remove open coded management of long_name_allocated member X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7e155d4d5e2912f75443c18c02dd6f1dbd4eef84;p=linux-beck.git perf symbols: Remove open coded management of long_name_allocated member Instead of expecting callers to set this member accodingly so that later at dso destruction it can, if needed, be correctly free()d, make it a requirement by passing it as a parameter to dso__set_long_name.
