Linux gen_pool allocator replacement?

[Sebastian Huber]

Hello,

I try currently to port a BSD licensed Linux network interface driver to 
FreeBSD. This driver uses the gen_pool allocator

http://elixir.free-electrons.com/linux/latest/source/include/linux/genalloc.h

for example here

https://github.com/torvalds/linux/blob/master/drivers/soc/fsl/qbman/qman.c#L2707

Does someone know if something similar exits in the FreeBSD kernel? I 
cannot use UMA since the pool management data must reside outside the 
managed memory area. One use case in this driver seems just to manage a 
range of integers, so no actual memory allocation. For this I could 
probably use UNR(9), but a general gen_pool allocator replacement would 
be nice.
