Hi,
Linux 2.6.0-test5 is reporting a lot of the following messages in dmesg on
one of the machines here:
RPC svc_write_space: some sleeping on f6ce8900
It is triggered by the following code in svcsock.c
static void
svc_write_space(struct sock *sk)
{
struct svc_sock *svsk = (struct svc_sock *)(sk->sk_user_data);
if (svsk) {
dprintk("svc: socket %p(inet %p), write_space busy=%d\n",
svsk, sk, test_bit(SK_BUSY, &svsk->sk_flags));
svc_sock_enqueue(svsk);
}
if (sk->sk_sleep && waitqueue_active(sk->sk_sleep)) {
printk(KERN_WARNING "RPC svc_write_space: some sleeping on %p\n",
svsk);
wake_up_interruptible(sk->sk_sleep);
}
}
Can someone explain what the warning is about?
-Udo.
