1. Prominent features

1.1. New BFQ I/O scheduler for a more reponsive desktop

BFQ (Budget Fair Queuing) is a new I/O scheduler. For personal systems, BFQ provides low latency for interactive applications, low latency for soft real-time applications, higher speed for code-development tasks, high throughput, and strong fairness, bandwidth and delay guarantees. For servers, besides the same benefits as above, BFQ guarantees: audio and video-streaming with zero or very low jitter and drop rate; fast retrieval of WEB pages and embedded objects; real-time recording of data in live-dumping applications (e.g., packet logging); responsiveness in local and remote access to a server. For more details and benchmarks, see the [https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/block/bfq-iosched.txtDocumentation] or the [http://algo.ing.unimo.it/people/paolo/disk_sched/ project site]

1.2. New Kyber I/O scheduler

The Kyber I/O scheduler is a low-overhead scheduler suitable for multiqueue and other fast devices. Given target latencies for reads and synchronous writes, it will self-tune queue depths to achieve that goal, similary to blk-wbt.
