*Summary*
4 1 Greg Farnum
There are a lot of feature tickets in the CephFS backlog which the team hasn't prioritized enough to get done, but could provide value to users and are feasible for implementation by new developers. In this session I/we will go through some of them and discuss likely designs and points of interest.
