From: Xiubo Li <xiubli@xxxxxxxxxx> This will fix the issue in [1], and only send metrics to MDS that supported, and for Quincy or higher ceph versions since it's safe will force to send all the metrics. This could make sure the early Quincy ceph versions still could get the metric which haven't backported [2], which will fill the metric bits supported by MDS when opening the sessions, no need to enable the force_ignore_metric_bits module parameter.
