__LINK_STATE_RX_SCHED still exist in kernel 2.6.23.8.
Netdevice.h:
/* Test if receive needs to be scheduled */
static inline int __netif_rx_schedule_prep(struct net_device *dev)
{
return !test_and_set_bit(__LINK_STATE_RX_SCHED, &dev->state);
}
/* Test if receive needs to be scheduled but only if up */
static inline int netif_rx_schedule_prep(struct net_device *dev)
{
return netif_running(dev) && __netif_rx_schedule_prep(dev);
}
Dev.c:
int dev_close(struct net_device *dev)
{
...
while (test_bit(__LINK_STATE_RX_SCHED, &dev->state)) {
/* No hurry. */
msleep(1);
}
...
}
Test_bit() in dev_close() maybe between the calling of netif_running() and
__netif_rx_schedule_prep() in netif_rx_schedule_prep.
