md: superblock changes for PPL Include information about PPL location and size into mdp_superblock_1 and copy it to/from rdev. Because PPL is mutually exclusive with bitmap, put it in place of 'bitmap_offset'. Add a new flag MD_FEATURE_PPL for 'feature_map', analogically to MD_FEATURE_BITMAP_OFFSET. Add MD_HAS_PPL to mddev->flags to indicate that PPL is enabled on an array. Signed-off-by: Artur Paszkiewicz <artur.paszkiewicz@intel.com> Signed-off-by: Shaohua Li <shli@fb.com>
