[PATCH v2 0/7] mdadm support for Partial Parity Log

[Artur Paszkiewicz <artur.paszkiewicz@intel.com>]

This is the mdadm part of the PPL functionality. It adds a new parameter to
mdadm to allow selecting the RWH policy for an array. Other changes include
displaying the RWH policy in the output from --detail and --examine.

As with the kernel patches sent earlier, all of this is currently targeted and
tested with IMSM and native MD v1.1 and v1.2 metadata arrays.

v2:
- Rebased to latest mdadm code.
- Fixed runtime policy switching.
- Recognize IMSM PPL journal drive correctly.
- Removed bitfields from imsm_dev.
- Made dirty/consistent checks in imsm_set_array_state() more readable.
- Added comment about calculating sb_start.
