This is the mdadm part of the PPL functionality. It adds a new parameter to mdadm to allow selecting the consistency policy for an array and implements PPL as one of the policies. All of this is currently targeted and tested with imsm and super1 metadata arrays. The kernel patches are available on Shaohua's md tree on the for-next branch. v4: - Rebased to latest mdadm code. - Fixed a mistake in Makefile. - Added descriptions for --consistency-policy in --help messages. v3: - Rebased to latest mdadm code. - Replaced --rwh-policy with --consistency-policy. - Adjusted to the kernel interface changes. - Write the initial ppl header in mdadm when creating an array. - Validate ppl when starting an imsm array. - Support for --update. - Support also 1.0 metadata. - Use Grow mode for enabing or disabling ppl for an active array. 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.
