Hmmm... yean, the race condition could be an issue as multiple msi allocation might fail even if the driver can and explicitly handle multiple allocation if the quota gets reduced inbetween.
BTW, should we care about the quota getting increased inbetween? That would entail.. kind of pci_get_msi_limit() :), but IMHO it is not worth it.
