      [DLM] add lock timeouts and warnings [2/6] · 3ae1acf9
      David Teigland authored
      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.
