Sage,
On master after a vstart even without any pools created, OSDs are
continuously logging these messages.
I don't know if the continuous calls to BlueStore::LRUCache::_trim() or
BlueStore::TwoQCache::_trim() are expected.
We trim in a loop in the mempool thread, but post nautilus I wan to
change that to trim on write.

I introduced this one with the autotuner, though I'm planning to move
that out into it's own manager precisely to get it out of bluestore
debugging.
