[v2,0/5] lightnvm: Flexible metadata

Message

Igor Konopko Oct. 22, 2018, 10:36 a.m. UTC

This series of patches extends the way how pblk can
store L2P sector metadata. After this set of changes
any size of NVMe metadata (including 0) is supported.

Patches are rebased on top of block/for-next since
there was no ocssd/for-4.21 branch yet.

Changes v1 --> v2:
-Revert sector meta size back to 16b for pblk
-Dma pool for larger oob meta are handled in core instead of pblk
-Pblk oob meta helpers uses __le64 as input outpu instead of u64
-Other minor fixes based on v1 patch review

  lightnvm: pblk: Move lba list to partial read context
  lightnvm: pblk: Helpers for OOB metadata
  lightnvm: Flexible DMA pool entry size
  lightnvm: Disable interleaved metadata
  lightnvm: pblk: Support for packed metadata
