Luca Miccio 7535afccf9 block,bfq: Disable writeback throttling ... [ Upstream commit b5dc5d4d1f ] Similarly to CFQ, BFQ has its write-throttling heuristics, and it is better not to combine them with further write-throttling heuristics of a different nature. So this commit disables write-back throttling for a device if BFQ is used as I/O scheduler for that device.
