This patchset contains small changes that improve the performance of memory map updates. The patches reduce the execution time of ib_umem_odp_unmap_dma_pages when invalidating 4MB of memory from 46us to 13us. This amounts to a reduction of about 30% in the total execution time of the invalidation flow. As this flow is called from the mmu_notifier hooks, this optimization can have a system-wide performance impact. v1: Apply review comment by Sagi Grimberg Guy Shapiro (2): IB/core: dma map/unmap locking optimizations IB/core: dma unmap optimizations drivers/infiniband/core/umem_odp.c | 12 +++++------- 1 files changed, 5 insertions(+), 7 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
