Merge tag 'dm-3.20-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper changes from Mike Snitzer: - The most significant change this cycle is request-based DM now supports stacking ontop of blk-mq devices. This blk-mq support changes the model request-based DM uses for cloning a request to relying on calling blk_get_request() directly from the underlying blk-mq device. An early consumer of this code is Intel's emerging NVMe hardware; thanks to Keith Busch for working on, and pushing for, these changes. - A few other small fixes and cleanups across other DM targets. * tag 'dm-3.20-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm: inherit QUEUE_FLAG_SG_GAPS flags from underlying queues dm snapshot: remove unnecessary NULL checks before vfree() calls dm mpath: simplify failure path of dm_multipath_init() dm thin metadata: remove unused dm_pool_get_data_block_size() dm ioctl: fix stale comment above dm_get_inactive_table() dm crypt: update url in CONFIG_DM_CRYPT help text dm bufio: fix time comparison to use time_after_eq() dm: use time_in_range() and time_after() dm raid: fix a couple integer overflows dm table: train hybrid target type detection to select blk-mq if appropriate dm: allocate requests in target when stacking on blk-mq devices dm: prepare for allocating blk-mq clone requests in target dm: submit stacked requests in irq enabled context dm: split request structure out from dm_rq_target_io structure dm: remove exports for request-based interfaces without external callers
