Hi,

while browsing through the network drivers about the etherleak issue i
found that some drivers have:

#ifdef CONFIG_SMP
        spin_lock_irqsave(...)
#endif

and some just:

        spin_lock_irqsave(...)

or similar.
Which version should be practiced? i thought spinlocks are irrelevant
without SMP so we should use #ifdef to shorten the execution path.

Regards,
Maciej Soltysiak
