reg_set_min_max	Adjusts the register min/max values in the case that the dst_reg is the* variable register that we are working on, and src_reg is a constant or we're* simply doing a BPF_K check.* In JEQ/JNE cases we also adjust the var_off values.
reg_set_min_max_inv	Same as above, but for the case that dst_reg holds a constant and src_reg is* the variable reg.
