Hi ! I stumbled accross what might be a bug on out of order architecture:
netif_poll_enable() only does a clear_bit(). However, netif_poll_disable/enable pairs are often used as simili-spinlocks. (netif_poll_enable() has pretty much spin_lock semantics except that it schedules instead of looping). Thus, shouldn't netif_poll_disable() do an smp_wmb(); before clearing the bit to make sure that any stores done within the poll-disabled section are properly visible to the rest of the system before clearing the bit ?
