See http://www.infradead.org/rpr.html Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org From: He Kuang This patch moves the reference of buildid dir to 'symfs/.debug' and skips the local buildid dir when '--symfs' is given, so that every single file opened by perf is relative to symfs directory now.
