  1. pblk: Physical Block Device Target
  2. ==================================
  3. pblk implements a fully associative, host-based FTL that exposes a traditional
  4. block I/O interface. Its primary responsibilities are:
  5. - Map logical addresses onto physical addresses (4KB granularity) in a
  6. logical-to-physical (L2P) table.
  7. - Maintain the integrity and consistency of the L2P table as well as its
  8. recovery from normal tear down and power outage.
  9. - Deal with controller- and media-specific constrains.
  10. - Handle I/O errors.
  11. - Implement garbage collection.
  12. - Maintain consistency across the I/O stack during synchronization points.
