Will do, I'll drop the costly_order gate and bail on __GFP_NORETRY.
Andrew, since you dropped v5 and restored v4 in mm-unstable, I'll send a
v6 (v4 plus the above change) unless you'd rather have an incremental
patch on top of v4. Let me know if anything else is needed on my side.
Thanks,
Salvatore
