  [PATCH 01/14] perf machine: Pass correct string to dso__adjust_kmod_long_name Arnaldo Carvalho de Melo <acme@kernel.org> - 2015-12-07 23:30 +0100

#1286019 — [PATCH 01/14] perf machine: Pass correct string to dso__adjust_kmod_long_name

From: Wang Nan <wangnan0@huawei.com>

There's a mistake in dso__adjust_kmod_long_name() that it use strdup()
to dup the new long_name of a dso, but passes the original string to
dso__set_long_name(). Which causes random crash during cleanup.
