This series of patches introduce some more flexibility in pblk related to OOB meta: -ability to use different sizes of metadata (previously fixed 16b) -ability to use pblk on drives without metadata -ensuring that extended (interleaved) metadata is not in use
I belive that most of this patches, maybe except of number 4 (Support for packed metadata) are rather simple, so waiting for comments especially about this one.
