Date: Wed, 8 Sep 2010 22:48:48 +0900 From: Namhyung Kim <namhyung@...il.com> To: "David S. Miller" <davem@...emloft.net>, netdev@...r.kernel.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 2/2] net/core: add lock context change annotations in net/core/sock.c __lock_sock() and __release_sock() releases and regrabs lock but were missing proper annotations. Add it. This removes following warning from sparse. (Currently __lock_sock() does not emit any warning about it but I think it is better to add also.) net/core/sock.c:1580:17: warning: context imbalance in '__release_sock' - unexpected unlock Signed-off-by: Namhyung Kim <namhyung@...il.com> --- net/core/sock.c | 4 ++++ 1 files changed, 4 insertions(+), 0 deletions(-) diff --git a/net/core/sock.c b/net/core/sock.c index b05b9b6..f3a06c4 100644 --- a/net/core/sock.c +++ b/net/core/sock.c @@ -1557,6 +1557,8 @@ struct sk_buff *sock_alloc_send_skb(struct sock *sk, unsigned long size, EXPORT_SYMBOL(sock_alloc_send_skb); static void __lock_sock(struct sock *sk) + __releases(&sk->sk_lock.slock) + __acquires(&sk->sk_lock.slock) { DEFINE_WAIT(wait); @@ -1573,6 +1575,8 @@ static void __lock_sock(struct sock *sk) } static void __release_sock(struct sock *sk) + __releases(&sk->sk_lock.slock) + __acquires(&sk->sk_lock.slock) { struct sk_buff *skb = sk->sk_backlog.head; -- 1.7.2.2 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
