The general advice[1] on this is not to try and use a 3.x kernel with
CephFS.  The only exception is if your distro provider is doing
special backports (latest RHEL releases have CephFS backports).  This
causes some confusion, because a number of distros that have shipped
"stable" kernels with older, known unstable CephFS code.

If you're building your own kernels then you definitely want to be on
a recent 4.x
