Date: Thu, 23 Jul 2015 12:52:31 +0800 Message-Id: <24a0bb6f3554c13461e8336d52a8585308efd50b.1437627016.git.lv.zheng@intel.com> X-Mailer: git-send-email 1.7.10 In-Reply-To: References: Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org ACPICA commit 9dcd124e914e87495fbd1786d9484b962e0823e0 This patch adds back pointing reference of the namespace node for a method operand. The namespace node then can be used in acpi_ds_terminate_control_method() to obtain method full path to be used by tracing facilities. Lv Zheng.
