  Removed the section mismatch message:
  WARNING: fs/dlm/dlm.o(.init.text+0x132): Section mismatch in reference from the function init_module() to the function .exit.text:dlm_netlink_exit()

  Since dlm_netlink_exit() is called in the init_dlm() error handling,
  the __exit annotation has been removed.

• 84d8cd69a   [DLM] timeout fixes ... Browse Code »

  Various fixes related to the new timeout feature:
  - add_timeout() missed setting TIMEWARN flag on lkb's when the
  TIMEOUT flag was already set
  - clear_proc_locks should remove a dead process's locks from the
  timeout list
  - the end-of-life calculation for user locks needs to consider that
  ETIMEDOUT is equivalent to -DLM_ECANCEL
  - make initial default timewarn_cs config value visible in configfs
  - change bit position of TIMEOUT_CANCEL flag so it's not copied to
  a remote master node
  - set timestamp on remote lkb's so a lock dump will display the time
  they've been waiting

• 3ae1acf93   [DLM] add lock timeouts and warnings [2/6] ... Browse Code »

  New features: lock timeouts and time warnings. If the DLM_LKF_TIMEOUT
  flag is set, then the request/conversion will be canceled after waiting
  the specified number of centiseconds (specified per lock). This feature
  is only available for locks requested through libdlm (can be enabled for
  kernel dlm users if there's a use for it.)

  If the new DLM_LSFL_TIMEWARN flag is set when creating the lockspace, then
  a warning message will be sent to userspace (using genetlink) after a
  request/conversion has been waiting for a given number of centiseconds
  (configurable per node). The time warnings will be used in the future
  to do deadlock detection in userspace.
