From: Eric Dumazet <edumazet@google.com> We want to call inet_frags_init() earlier. This is a prereq to "inet: frags: use rhashtables for reassembly units" Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net> (cherry picked from commit 5b975bab23615cd0fdf67af6c9298eb01c4b9f61) --- net/ipv6/reassembly.c | 25 ++++++++++++++----------- 1 file changed, 14 insertions(+), 11 deletions(-)
