The patch (commit 8a965b3baa89ffedc73c0fbc750006c631012ced) merely changed the sequence of
slab creation to address an issue in SLAB.

Hmmm.. But if KMALLOC_SHIFT_LOW is higher than 6 or 7 then the creation of
the non-power of two slab could be skipped as a result of the patch. But
we should not need them in those cases.

Can I see the kernel config?

What is the value of KMALLOC_SHIFT_LOW?

Can you figure out which kernel slab the function is trying to access?
