Subject: [PATCH perf/core v7 01/21] tools/perf: Fix lsdir to set errno correctly
Date: Wed, 11 May 2016 22:51:27 +0900 [thread overview]
Message-ID: <20160511135127.23943.40644.stgit@devbox> (raw)
In-Reply-To: <20160511135110.23943.38738.stgit@devbox>
Fix lsdir() to set correct positive error number (ENOMEM).
Since "errno" must have a positive error number instead of
negative number, fix lsdir to set it correctly.
