| |
Hi Linus,
It's a nice and quiet round this time, since most of the tricky stuff has been pushed to 3.5 to give it more time to mature. 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. Documentation: Add sysfs ABI change for cfq's target latency.
