Merge branch 'for-4.7/core' of git://git.kernel.dk/linux-block
Pull core block layer updates from Jens Axboe:
"This is the core block IO changes for this merge window. 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"
