• 4b1977698   block: Prevent hang_check firing during long I/O ... Browse Code »

  During long I/O operations, the hang_check timer may fire,
  trigger stack dumps that unnecessarily alarm the user.

  Eg. hdparm --security-erase NULL /dev/sdb ## can take *hours* to complete

  So, if hang_check is armed, we should wake up periodically
  to prevent it from triggering. This patch uses a wake-up interval
  equal to half the hang_check timer period, which keeps overhead low enough.

  Remove all the trivial wrappers for the cmd_type and cmd_flags fields in
  struct requests. This allows much easier grepping for different request
  types instead of unwinding through macros.

  RQ_NOMERGE_FLAGS already clears defines which REQ flags aren't
  mergeable. There is no reason to specify it superflously. It only
  adds to confusion. Don't set REQ_NOMERGE for barriers and requests
  with specific queueing directive. REQ_NOMERGE is now exclusively used
  by the merging code.

  All the users of blk_end_sync_rq has gone (they are converted to use
  blk_execute_rq). This unexports blk_end_sync_rq.

  For blk_pm_resume_request() requests (which are used only by IDE subsystem
  currently) the queue is stopped so we need to call ->request_fn explicitly.

  Thanks to:
  - Rafael for reporting/bisecting the bug
  - Borislav/Rafael for testing the fix

  This is a preparation for converting IDE to use blk_execute_rq().
