The question is not whether there's an alternative function.
The kernel does not waste memory for all users by providing a fixed API
for external modules, the purpose of the kernel is to provide everything
required for what is shipped with the kernel.
Simply send the patch adding the exports when you submit your module for
inclusion in the kernel.

That sounds strange considering that slab and slob AFAIR never exported
this symbol and only slub in 2.6.22 and 2.6.23 exports it.

The interesting fact is that there are zero in-kernel modules using it.
