   This happened once and is not reproducible.
   There appears to be initialization window where netlink data can
   arrive before socket slab cache is initialized or something like that.
   Probably a packet has to arrive at just the right time or something similar.
   
It's oopsing on sock_inode_cachep.  We init that in sock_init()
which is invoked explicitly by do_basic_setup().

The calltrace is back into netlink_kernel_create via rtnetlink_init
via netlink_proto_init.  netlink_proto_init was recently changed
into a subsys initcall.

Because it is a subsys initcall, it must be invoked after sock_init()
and therefore the sock_inode_cachep must be initialized properly at
this point.

I have no idea how your trace is possible besides possible mem
corruption.
