      [PATCH] separate bdi congestion functions from queue congestion functions · 3fcfab16
      Andrew Morton authored
      
      
      Separate out the concept of "queue congestion" from "backing-dev congestion".
      Congestion is a backing-dev concept, not a queue concept.
      
      The blk_* congestion functions are retained, as wrappers around the core
      backing-dev congestion functions.
      
      This proper layering is needed so that NFS can cleanly use the congestion
      functions, and so that CONFIG_BLOCK=n actually links.
