to get the following device-mapper updates for 3.6.
Thanks,
Alasdair
----------------------------------------------------------------
Device-mapper updates for 3.6:
- Flip the thin target into new read-only or failed modes if errors
are detected;
- Handle chunk sizes that are not powers of two in the snapshot and
thin targets;
- Provide a way for userspace to avoid replacing an already-loaded
multipath hardware handler while booting;
- Reduce dm_thin_endio_hook slab size to avoid allocation failures;
- Numerous small changes and cleanups to the code.
