Again lustre upgrade troubles: unable to mount after upgrade to 2.10.x

The failure is following:

LDISKFS-fs (sda): Unrecognized mount option "context="unconfined_u:object_r:user_tmp_t:s0"" or missing value

But Selinux is disabled so we should remove that mount options.
To fix it:

tunefs.lustre --mountfsoptions="user_xattr,errors=remount-ro" /dev/sda

mount a expected.
