And for sake of completeness. Here is some debug output with a kernel
that had your "slub: Handle NULL parameter in kmem_cache_flags" patch
applied. And of course there were a couple of unnamed slabs:
...
.bss : 0xc089fd80 - 0xc094cc4c ( 692 kB)
slub_debug_slabs (c2956a08): skbuff_fclone_cache, name (c06fc90c): kmem_cache_node

→ slub_debug_slabs (c2956a08): skbuff_fclone_cache, name ( (null)): (null)

SLUB: HWalign=64, Order=0-3, MinObjects=0, CPUs=4, Nodes=1
...
The third one is wheree the panic happened w/o the fix.
