Description
These counters actually reflect the LRU, which is a collection of dentries, not inodes.
mds_mem.ino on the other hand, is actually the number of inodes in cache.
These names need cleaning up to be a bit less misleading, especially as the LRU size is incremented e.g. for stats on files that don't exist (because we create null dentries). Maybe the LRU-based counters should be called cache_used, cache_size etc to reflect what they're really telling us.
