It depends :-) Most of the time, the packets will be allocated at sendmsg() time for the user, and thus GFP_KERNEL. But the flags may be different if, for example, the packet is being allocated for the NFS client/server code, or some asynchronous packet generated at software interrupt time (TCP ACKs, ICMP replies, etc.). -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
