Doc Text:
.Memory growth because of onodes is now controlled Previously, the default value for the option `bluestore_cache_trim_max_skip_pinned` was 64 which was very low for large clusters. Since this option controlled the rate of trimming onodes and with current default value, it could have led to a buildup of onodes causing memory growth. With this release, the default value of bluestore_cache_trim_max_skip_pinned` is 1000 and the memory growth is controlled.
