After a few hectic block IO core changes for 3.3 and 3.2, I'm quite happy with a slow round. Really minor stuff in here, the only real functional change is making the auto-unplug threshold a per-queue entity. The threshold is set so that it's low enough that we don't hold off IO for too long, but still big enough to get a nice benefit from the batched insert (and hence queue lock cost reduction). For raid configurations, this currently breaks down. Please pull. git://git.kernel.dk/linux-block.git for-3.4/core Andi Kleen (1): block: use lockdep_assert_held for queue locking Dan Carpenter (1): block: blk_alloc_queue_node(): use caller's GFP flags instead of GFP_KERNEL Shaohua Li (1): block: make auto block plug flush threshold per-disk based Tao Ma (2): block: Make cfq_target_latency tunable through sysfs.
