pblk: Physical Block Device Target

pblk implements a fully associative, host-based FTL that exposes a traditional
block I/O interface. Its primary responsibilities are:

  • Map logical addresses onto physical addresses (4KB granularity) in a
    logical-to-physical (L2P) table.
  • Maintain the integrity and consistency of the L2P table as well as its
    recovery from normal tear down and power outage.
  • Deal with controller- and media-specific constrains.
  • Handle I/O errors.
  • Implement garbage collection.
  • Maintain consistency across the I/O stack during synchronization points.
