From c4322884ed2132beee95a16234035ad7cc991f09 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 25 Oct 2021 15:13:42 -0700 Subject: [PATCH] tcp: remove unneeded code from tcp_stream_alloc_skb() Aligning @size argument to 4 bytes is not needed. The header alignment has nothing to do with @size. It really depends on skb->head alignment and MAX_TCP_HEADER. Signed-off-by: Eric Dumazet Acked-by: Soheil Hassas Yeganeh Signed-off-by: David S.
