The patchset is against mq-maps branch of block tree, feel free to integrate into the whole patchset of multiple queue maps. Thanks, Ming Jens Axboe (1): irq: add support for allocating (and affinitizing) sets of IRQs Ming Lei (3): Revert "irq: add support for allocating (and affinitizing) sets of IRQs" irq: move 2-stage irq spread into one helper irq: pass first vector to __irq_build_affinity_masks kernel/irq/affinity.c | 119 +++++++++++++++++++++++++++++++------------------- 1 file changed, 75 insertions(+), 44 deletions(-) Cc: Thomas Gleixner Cc: linux-kernel@vger.kernel.org Cc: Hannes Reinecke Cc: Ming Lei Cc: Keith Busch Cc: Sagi Grimberg -- 2.9.5
