This results in lock_dlm incorrectly switching to the alternate lock mode when returning the result to gfs which then asserts when it sees the wrong lock state. The fix is to propagate the cleared sbflags value to the master node when the lock is requested. QA's d_rwrandirectlarge test triggers this bug very quickly.
