If I understand the code correctly, you are setting the
pf_pool_limits[].pp to NULL in pfattach(), since you commented out the
ZONE_CREATE parts, well, all xxx_pl is by default NULL.  So the ioctl
actually hi the pf_pool_limits[].pp == NULL, and EINVAL is returned.

kmalloc also has its own limit, you could use kmalloc_raise_limit() to
configure it.
