It is called from mm/swap.c. I don't think you actually want to be
reducing the number of buffers. The number of buffers gets reduced
automatically when the system runs out of memory. It then starts
swapping and re-useing buffers as user memory.
The relevent routine is mm/swap.c::get_free_page(int priority);
