What we've done in the past here is to use (GFP_ATOMIC & ~__GFP_HIGH). It amounts to the same thing, but it carries some semantic meaning: "whatever GFP_ATOMIC measn, only don't dip into page reserves".
Plus it future-safes us against changes in GFP_ATOMIC.
I'll make that change. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
