This is in our testing branch and should go to Linus the next time we send him stuff for merge. Unfortunately there's nobody doing CephFS kernel backports at this time so you'll need to wait for that to come out or spin your own. :( -Greg On Tue, Jan 27, 2015 at 10:46 AM, Christopher Armstrong

Thanks Greg. Perhaps this is a motivation for us to switch to ceph-fuse from the kernel client - at least that way, we could easily upgrade for bug fixes without waiting for a new kernel. Chris On Wed, Jan 28, 2015 at 9:32 AM, Gregory Farnum g...@gregs42.com wrote: This is in our testing
