Subject: [PATCHv3 perf/core 4/6] tools perf util: Make rm_rf(path) argument const
Date: Thu, 26 Jan 2017 13:19:59 -0800
Message-ID: <20170126212001.14103-5-joe@ovn.org> (raw)
In-Reply-To: <20170126212001.14103-1-joe@ovn.org>

rm_rf() doesn't modify its path argument, and a future caller will pass
a string constant into it to delete.
