Budget Fair Queuing
Budget Fair Queuing (BFQ) is a proportional-share I/O scheduler derived from the CFQ scheduler. BFQ also creates a request queue for each process in the system for any given block device, but unlike CFQ, BFQ tries to distribute device throughput instead of the device time.

To use when the BFQ I/O scheduler is added to the official mainline:
 * The BFQ I/O scheduler
 * The return of the BFQ I/O scheduler
 * Paper: Evolution of the BFQ Storage-I/O Scheduler (PDF)
