Hi Linus,
The DM tree is based on the block tree for this cycle because a fair
amount of my time was spent working on the percpu inflight IO counters
changes and other block fixes (which impact DM) that are in Jens' block
pull.
The following changes since commit cd19181bf9ad4b7f40f2a4e0355d052109c76529:
blk-mq: enable IO poll if .nr_queues of type poll > 0 (2018-12-17 21:35:07
-0700)
are available in the Git repository at:

dm: do not allow readahead to limit IO size (2018-12-18 14:23:41 -0500)
Please pull, thanks.
Mike
----------------------------------------------------------------
- Eliminate a couple indirect calls from bio-based DM core.
- Fix DM to allow reads that exceed readahead limits by setting io_pages
in the backing_dev_info.
- A couple code cleanups in request-based DM.
- Fix various DM targets to check for device sector overflow if
CONFIG_LBDAF is not set.
- Use u64 instead of sector_t to store iv_offset in DM crypt; sector_t
isn't large enough on 32bit when CONFIG_LBDAF is not set.
- Performance fixes to DM's kcopyd and the snapshot target focused on
limiting memory use and workqueue stalls.
- Fix typos in the integrity and writecache targets.
- Log which algorithm is used for dm-crypt's encryption and
dm-integrity's hashing.
- Fix false -EBUSY errors in DM raid target's handling of check/repair
messages.
- Fix DM flakey target's corrupt_bio_byte feature to reliably corrupt
the Nth byte in a bio's payload.
