slip: fix NOHZ local_softirq_pending 08 warning

2011-08-08T05:14:45+00:00

When using nanosleep() in an userspace application we get a ratelimit warning:

	NOHZ: local_softirq_pending 08

According to 481a8199142c050b72bff8a1956a49fd0a75bbe0 the problem is caused by
netif_rx() function. This patch replaces netif_rx() with netif_rx_ni() which
has to be used from process/softirq context.

slip: remove dead code within the slip initialization

2011-07-13T09:31:39+00:00

This following code contains a dead "if (dev).." block:
        ...
        for (i = 0; i < slip_maxdev; i++) {
                dev = slip_devs[i];
                if (dev == NULL)
                        break;
        }
        /* Sorry, too many, all slots in use */
        if (i >= slip_maxdev)
                return NULL;

        if (dev) {
                sl = netdev_priv(dev);
                if (test_bit(SLF_INUSE, &sl->flags)) {
                        unregister_netdevice(dev);
                        dev = NULL;
                        slip_devs[i] = NULL;
                }
         }
        ...
The reason is that the code starting with "if (dev).." is never called as
when we found an empty slot (dev == NULL) we break the loop and "if (dev).."
not works eiter the loop ends and we get out with "i >= slip_maxdev".

slip: remove redundant check slip_devs for NULL

2011-07-13T09:31:39+00:00

As slip_devs is initialized on module load stage there is no reason to
check it for NULL anywhere instead of the deinitialization routine because
if we can't get enough memory on startup we don't run at all.

slip: fix MTU comparation operation when reallocating buffers

2011-07-13T09:31:39+00:00

In sl_realloc_bufs() there is no reason to check if the requested MTU greater
than or equal to the current MTU value as this function called only
when requested
MTU not equals to the current value. So, the ">=" operation can be
safely replaced
with the ">".
