Tested: oqq130:~# cat /proc/sys/net/core/optmem_max 131072 oqq130:~# echo 1000000 >/proc/sys/net/core/optmem_max oqq130:~# cat /proc/sys/net/core/optmem_max 1000000 oqq130:~# unshare -n oqq130:~# cat /proc/sys/net/core/optmem_max 131072 oqq130:~# exit logout oqq130:~# cat /proc/sys/net/core/optmem_max 1000000 Signed-off-by: Eric Dumazet <edumazet@google.com> Reviewed-by: Willem de Bruijn <willemb@google.com> Acked-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.
