      net pcmcia: worklimit reaches -1 · b9bdcd9b
      由 Roel Kluin 提交于 
      with while (--worklimit >= 0); worklimit reaches -1 after the loop. In
3c589_cs.c this caused a warning not to be printed.

In 3c574_cs.c contrastingly, el3_rx() treats worklimit differently:

static int el3_rx(struct net_device *dev, int worklimit)
{
	while (--worklimit >= 0) { ... }
	return worklimit;
}

el3_rx() is only called by function el3_interrupt(): twice:

static irqreturn_t el3_interrupt(int irq, void *dev_id)
{
        int work_budget = max_interrupt_work;
	while(...) {
		if (...)
			work_budget = el3_rx(dev, work_budget);
		if (...)
			work_budget = el3_rx(dev, work_budget);
		if (--work_budget < 0) {
		        ...
		        break;
		}
	}
}
The error path can occur 2 too early.

      net: fix tokenring license · 42224745
      由 Meelis Roos 提交于 
      Currently, modular tokenring ("tr") lacks a license and fails to load:

tr: module license 'unspecified' taints kernel.
tr: Unknown symbol proc_net_fops_create

Beacuse of this, no tokenring driver can load if it depends on modular 
tr. Fix this by adding GPL module license as it is in the kernel.

With this fix, tr module loads fine and tms380 driver also loads. Well, 
it does'nt work but that's a different bug.

      netlink: invert error code in netlink_set_err() · 4843b93c
      由 Pablo Neira Ayuso 提交于 
      The callers of netlink_set_err() currently pass a negative value
as parameter for the error code. However, sk->sk_err wants a
positive error value. Without this patch, skb_recv_datagram() called
by netlink_recvmsg() may return a positive value to report an error.

Another choice to fix this is to change callers to pass a positive
error value, but this seems a bit inconsistent and error prone
to me. Indeed, the callers of netlink_set_err() assumed that the
(usual) negative value for error codes was fine before this patch :).

This patch also includes some documentation in docbook format
for netlink_set_err() to avoid this sort of confusion.
