From 4eb26d3cd41b6bcbd3e12e85bc9e4f36f47eb430 Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Thu, 27 May 2010 15:29:29 -0700 Subject: datapath: Check for skb_cow_head(), not skb_cow(). skb_cow() has been present since 2.6.12 or earlier, but skb_cow_head() was added only in 2.6.23, so we were checking for the wrong identifier here. --- acinclude.m4 | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'acinclude.m4') diff --git a/acinclude.m4 b/acinclude.m4 index cabe7d3a7..015bf6654 100644 --- a/acinclude.m4 +++ b/acinclude.m4 @@ -157,8 +157,8 @@ AC_DEFUN([OVS_CHECK_LINUX26_COMPAT], [ OVS_GREP_IFELSE([$KSRC26/include/linux/skbuff.h], [skb_copy_from_linear_data_offset], [OVS_DEFINE([HAVE_SKB_COPY_FROM_LINEAR_DATA_OFFSET])]) - OVS_GREP_IFELSE([$KSRC26/include/linux/skbuff.h], [skb_cow], - [OVS_DEFINE([HAVE_SKB_COW])]) + OVS_GREP_IFELSE([$KSRC26/include/linux/skbuff.h], [skb_cow_head], + [OVS_DEFINE([HAVE_SKB_COW_HEAD])]) OVS_GREP_IFELSE([$KSRC26/include/linux/skbuff.h], [skb_transport_header], [OVS_DEFINE([HAVE_SKBUFF_HEADER_HELPERS])]) OVS_GREP_IFELSE([$KSRC26/include/linux/skbuff.h], [skb_warn_if_lro], -- cgit v1.2.1
