From 269bd27e66037a7932cee6d6aa7ef7defd0bfe38 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Wed, 27 Sep 2006 18:32:28 -0700 Subject: [TCP]: struct tcp_sack_block annotations Some of the instances of tcp_sack_block are host-endian, some - net-endian. Define struct tcp_sack_block_wire identical to struct tcp_sack_block with u32 replaced with __be32; annotate uses of tcp_sack_block replacing net-endian ones with tcp_sack_block_wire. Change is obviously safe since for cc(1) __be32 is typedefed to u32. Signed-off-by: Al Viro Signed-off-by: David S.
