From 719bfeaae8104fca4ca5d47c02592b08682f14fa Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 15 Apr 2009 03:39:52 -0700 Subject: packet: avoid warnings when high-order page allocation fails Latest tcpdump/libpcap triggers annoying messages because of high order page allocation failures (when lowmem exhausted or fragmented) These allocation errors are correctly handled so could be silent.
