Description: Excessive recovery window
Details    : With AT enabled, the recovery window can be excessively long (6000+
	     seconds). To address this problem, we no longer use
	     OBD_RECOVERY_FACTOR when extending the recovery window (the connect
	     timeout no longer depends on the service time, it is set to
	     INITIAL_CONNECT_TIMEOUT now) and clients report the old service
	     time via pb_service_time.

Description: ldlm_cancel_pack()) ASSERTION(max >= dlm->lock_count + count)
Details    : If there is no extra space in the request for early cancels,
             ldlm_req_handles_avail() returns 0 instead of a negative value.

Once the unmatched stride IO mode is detected, shrink the stride-ahead window to 0.
if it does hit cache miss, and read-pattern is still stride-io mode,
does not reset the stride window, but also does not increase the stride
window length in this case.
