Using ksize() for skbs will crash your kernel for some configurations
because calling that function for memory allocated with
kmem_cache_alloc() is not supported by all the allocators (well,
SLOB).

So how about fixing the interface so that it can return an error
to indicate that the allocator doesn't support it? You're taking
away an entire interface just because an underlying implementation
that's used by a very small proportion of users doesn't do the
right thing.
