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.
