No worry there.  The reserved resources are subtracted from the above
log amounts (when expressed as a power-of-2:  1UL << log), and the
resulting amounts (<power-of-2> - reserved) returned to the user as
the device limits.
(check this out using ibv_devinfo)

Thus, the user CANNOT "shoot themselves in the foot".

(P.S. this patch is in OFED 1.3 -- do "modinfo mlx4_core" to see the
above module parameters ).
