Oh. I see now the problem. The kernel & kernel-core does not match the 
kernel-devel package version.
(e.g. after the initial install, I rushed to install zfs before updating 
the system packages)

$ sudo dnf list installed | grep kernel
abrt-addon-kerneloops.x86_64 2.7.0-2.fc23                    @anaconda
kernel.x86_64                          4.2.3-300.fc23

What an ooopsie. Simply running "dnf update", then a reboot "shutdown -r 
now", has aligned things now.

$ sudo zpool status
   pool: zfsmain

Closing off, in case someone else runs into this and finds this in the 
archives.
