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: Namhyung Kim The hroot_in and hroot_out are roots of hierarchy trees of hist entries. But when a hist entry is initialized by copying existing template entry, it sometimes has non-empty tree and copies it incorrectly. This is a problem especially when an event group is used since it creates dummy entries from already-processed entries in other event members.
