2019-08-28blkcg: implement blk-iocostTejun Heo
This patchset implements IO cost model based work-conserving proportional controller. While io.latency provides the capability to comprehensively prioritize and protect IOs depending on the cgroups, its protection is binary - the lowest latency target cgroup which is suffering is protected at the cost of all others. In many use cases including stacking multiple workload containers in a single system, it's necessary to distribute IO capacity with better granularity. One challenge of controlling IO resources is the lack of trivially observable cost metric. The most common metrics - bandwidth and iops - can be off by orders of magnitude depending on the device type and IO pattern. However, the cost isn't a complete mystery. Given several key attributes, we can make fairly reliable predictions on how expensive a given stream of IOs would be, at least compared to other IO patterns. The function which determines the cost of a given IO is the IO cost model for the device. This controller distributes IO capacity based on the costs estimated by such model. The more accurate the cost model the better but the controller adapts based on IO completion latency and as long as the relative costs across differents IO patterns are consistent and sensible, it'll adapt to the actual performance of the device. Currently, the only implemented cost model is a simple linear one with a few sets of default parameters for different classes of device. This covers most common devices reasonably well. All the infrastructure to tune and add different cost models is already in place and a later patch will also allow using bpf progs for cost models. Please see the top comment in blk-iocost.c and documentation for more details. v2: Rebased on top of RQ_ALLOC_TIME changes and folded in Rik's fix for a divide-by-zero bug in current_hweight() triggered by zero inuse_sum.

2019-07-20dt-bindings: riscv: Limit cpus schema to only check RiscV 'cpu' nodesRob Herring
Matching on the 'cpus' node was a bad choice because the schema is incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus schema which checks the general structure, it is also redundant to do so in the Risc-V CPU schema. The downside is one could conceivably mix different architecture's cpu nodes or have typos in the compatible string. The latter problem pretty much exists for every schema.

2019-07-20dt-bindings: Ensure child nodes are of type 'object'Rob Herring
Properties which are child node definitions need to have an explict type. Otherwise, a matching (DT) property can silently match when an error is desired. Fix this up tree-wide. Once this is fixed, the meta-schema will enforce this on any child node definitions.
