Unable to import pools when upgrading OSS from 2.10.3 to 2.11.51.

Steps:

All clients and servers set up with 2.10.3 lustre version.

2.11.51 ZFS version: zfs-0.7.8-1.el7

Upgraded OSS to 2.11.51 and tried to import pools but getting the following:

[root@onyx-70 ~]# modprobe zfs

zpool import lustre-ost2[ 5805.811988] spl: loading out-of-tree module taints kernel.
