That seems like a lot of assumptions. Is it really better than the existing GFP_ATOMIC which works basically the same? It has a lot more users that compete true, but likely the set of GFP_CRITICAL users would grow over time too and it would develop the same problem. I think if you really want to attack this problem and improve over the GFP_ATOMIC "best effort in smaller pool" approach you should probably add real reservations. And then really do a lot of testing to see if it actually helps. -Andi - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
