TBH I think that the kernel should rather rely on generic integer 
overflow/underflow checks for its allocation APIs, a bit like the size 
overflow plugin you can find in grsec.

pool_cache(9) are generally sufficient enough to handle arrays of object 
with a fixed size (behind the curtain), adding yet-another allocator 
would not address the various kmem_alloc/malloc() call sites that 
already exist in kernel.

Of course this opinion is just mine :)
