Kotresh HR c0de657d3f mds: throttle cap acquisition via readdir ... A trivial "find" command on a large directory hierarchy will cause the client to receive caps significantly faster than it will release. The MDS will try to have the client reduce its caps below the mds_max_caps_per_client limit but the recall throttles prevent it from catching up to the pace of acquisition. The solution is to throttle readdir from client. This patch does the same. The readdir is throttled on the condition that the number of caps acquired is greater than certain percentage of mds_max_caps_per_client (default is 10%) and cap acquisition via readdir is certain percentage of mds_max_caps_per_client (the default is 50%). When the above condition is met, the readdir request is retried after 'mds_cap_acquisition_throttle_retry_request_timeout' (default is 0.5) seconds.
