Merge tag 'dm-3.14-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/device...

Pull device mapper fixes from Mike Snitzer:
 "A few dm-cache fixes, an invalid ioctl handling fix for dm multipath,
  a couple immutable biovec fixups for dm mirror, and a few dm-thin
  fixes.

  There will likely be additional dm-thin metadata and data resize fixes
  to include in 3.14-rc6 next week.

  Note to stable-minded folks: Immutable biovecs were introduced in
  3.14, so the related fixups for dm mirror are not needed in stable@
  kernels"
