net: avoid unnecessary sock_flag() check when enable timestamp
The sock_flag() check is alreay inside sock_enable_timestamp(), so it is unnecessary checking it in the caller. void sock_enable_timestamp(struct sock *sk, int flag) { if (!sock_flag(sk, flag)) { ... } } Signed-off-by: Yafang Shao <laoar.shao@gmail.com> Signed-off-by: David S.
