v0.78 firefly
-------------
* The default leveldb cache size for the ceph-osd daemon has been
increased from 4 MB to 128 MB. This will increase the memory
footprint of that process but tends to increase performance of omap
(key/value) objects (used for CephFS and the radosgw). If memory in your
deployment is tight, you can preserve the old behavio by adding::
leveldb write buffer size = 0
leveldb cache size = 0
to your ceph.conf to get back the (leveldb) defaults.
