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