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."
