Thanks, -- Kiran P. -----Original Message----- From: Intel-wired-lan [mailto:intel-wired-lan-bounces@...ts.osuosl.org] On Behalf Of Jiang Liu Sent: Sunday, August 16, 2015 8:19 PM To: Andrew Morton; Mel Gorman; David Rientjes; Mike Galbraith; Peter Zijlstra; Wysocki, Rafael J; Tang Chen; Tejun Heo; Kirsher, Jeffrey T; Brandeburg, Jesse; Nelson, Shannon; Wyborny, Carolyn; Skidmore, Donald C; Vick, Matthew; Ronciak, John; Williams, Mitch A Cc: Luck, Tony; netdev@...r.kernel.org; x86@...nel.org; linux-hotplug@...r.kernel.org; linux-kernel@...r.kernel.org; linux-mm@...ck.org; intel-wired-lan@...ts.osuosl.org; Jiang Liu Subject: [Intel-wired-lan] [Patch V3 6/9] i40evf: Use numa_mem_id() to better support memoryless node Function i40e_clean_rx_irq() tries to reuse memory pages allocated from the nearest node. To better support memoryless node, use numa_mem_id() instead of numa_node_id() to get the nearest node with memory. This change should only affect performance.
