Nothing earth shattering in here, it's mostly just fixes. In detail: - Fix for a long standing issue where wrong ordering in blk-mq caused order_to_size() to spew a warning. From Bart. - Async discard support from Christoph. Basically just splitting our sync interface into a submit + wait part. - Add a cleaner interface for flagging whether a device has a write back cache or not. We've previously overloaded blk_queue_flush() with this, but let's make it more explicit. Drivers cleaned up and updated in the drivers pull request. From me. - Fix for a double check for whether IO accounting is enabled or not. From Michael Callahan. - Fix for the async discard from Mike Snitzer, reinstating the early EOPNOTSUPP return if the device doesn't support discards. - Also from Mike, export bio_inc_remaining() so dm can drop it's private copy of it. - From Ming Lin, add support for passing in an offset for request payloads. - Tag function export from Sagi, which will be used in NVMe in the drivers pull. - Two blktrace related fixes from Shaohua. - Propagate NOMERGE flag when making a request from a bio, also from Shaohua. - An optimization to not parse cgroup paths in blk-throttle, if we don't need to. From Shaohua.
