From 5dcf16df3ce48b2e4f798b1a11b5de2fc3cfd73a Mon Sep 17 00:00:00 2001 From: Wang Nan Date: Mon, 7 Dec 2015 02:36:25 +0000 Subject: [PATCH] perf machine: Pass correct string to dso__adjust_kmod_long_name 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.
