Merge tag 'dm-3.13-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper changes from Mike Snitzer:
 "A set of device-mapper changes for 3.13.

  Improve reliability of buffer allocations for dm messages with a small
  number of arguments, a couple path group initialization fixes for dm
  multipath, a fix for resizing a dm array, various fixes and
  optimizations for dm cache, a fix for device mapper's Kconfig menu
  indentation.

  Features added include:
   - dm crypt support for activating legacy CBC TrueCrypt containers
     (useful for forensics of these old TCRYPT containers)
   - reduced dm-cache memory requirements for each block in the cache
   - basic support for shrinking a dm-cache's cache (fast) device
   - most notably, dm-cache support for managing cache coherency when
     deploying dm-cache with sophisticated origin volumes (that support
     hardware snapshots and/or clustering): these changes come in the
     form of a new passthrough operation mode and a cache block
     invalidation interface"
