• 89a09141d   [PATCH] nfs: fix congestion control ... Browse Code »

  The current NFS client congestion logic is severly broken, it marks the
  backing device congested during each nfs_writepages() call but doesn't
  mirror this in nfs_writepage() which makes for deadlocks. Also it
  implements its own waitqueue.

  Replace this by a more regular congestion implementation that puts a cap on
  the number of active writeback pages and uses the bdi congestion waitqueue.

  Also always use an interruptible wait since it makes sense to be able to
  SIGKILL the process even for mounts without 'intr'.

• 3fcfab16c   [PATCH] separate bdi congestion functions from queue congestion functions ... Browse Code »

  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.
