staging/lustre/ldlm: Solve a race for LRU lock cancel This patch solves a race condition that the lock may be used again after LRU cancellation policy check. In that case, the lock may have locked or dirty pages that makes the policy check totally useless. The problem is solved by checking l_last_used at cancellation time therefore it can make sure that the lock has not been used.
