Merge tag 'dm-3.9-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm
Pull device-mapper update from Alasdair G Kergon: "The main addition here is a long-desired target framework to allow an SSD to be used as a cache in front of a slower device. Cache tuning is delegated to interchangeable policy modules so these can be developed independently of the mechanics needed to shuffle the data around. Other than that, kcopyd users acquire a throttling parameter, ioctl buffer usage gets streamlined, more mempool reliance is reduced and there are a few other bug fixes and tidy-ups." * tag 'dm-3.9-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm: (30 commits) dm cache: add cleaner policy dm cache: add mq policy dm: add cache target dm persistent data: add bitset dm persistent data: add transactional array dm thin: remove cells from stack dm bio prison: pass cell memory in dm persistent data: add btree_walk dm: add target num_write_bios fn dm kcopyd: introduce configurable throttling dm ioctl: allow message to return data dm ioctl: optimize functions without variable params dm ioctl: introduce ioctl_flags dm: merge io_pool and tio_pool dm: remove unused _rq_bio_info_cache dm: fix limits initialization when there are no data devices dm snapshot: add missing module aliases dm persistent data: set some btree fn parms const dm: refactor bio cloning dm: rename bio cloning functions ...
