dm cache: resolve small nits and improve Documentation (2013-11-12 13:11:09 -0500)
Please pull, thanks.
Mike
----------------------------------------------------------------
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.
