Replace occurrences of 'if (<bool expr> == <1|0>)' with 'if ([!]<bool expr>)' Replace occurrences of '<bool var> = (<non-bool expr>) ? true : false' with '<bool var> = <non-bool expr>'. Replace occurrence of '<bool var> = <non-bool expr>' with '<bool var> = !!<non-bool expr>' While the latter replacement is not really necessary, it is done here for consistency and clarity. No functional changes. Signed-off-by:

Most machines dont use UDP encapsulation (L2TP) Adds a static_key so that udp_queue_rcv_skb() doesnt have to perform a test if L2TP never setup the encap_rcv on a socket. Idea of this patch came after Simon Horman proposal to add a hook on TCP as well. If static_key is not yet enabled, the fast path does a single JMP . When static_key is enabled, JMP destination is patched to reach the real encap_type/encap_rcv logic, possibly adding cache misses. Signed-off-by:

Change get_tx_queues, drop unsused arg/return value real_tx_queues, and use return by value (with error) rather than call by reference. Probably bonding should just change to LLTX and the whole get_tx_queues API could disappear! Signed-off-by:

In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register() so we can drop the manual assignment. The patch was generated using the following coccinelle semantic patch: // <smpl> @@ identifier _driver; @@ struct spi_driver _driver = { .driver = { - .bus = &spi_bus_type, }, }; // </smpl> Signed-off-by:Lars-Peter Clausen <lars@metafoo.de> Cc: "David S.

The comparison operators were backwards in both garp_attr_lookup and garp_attr_create, so the entire GID rbtree was in reverse order. (There was no practical side effect to this though, except that PDUs were sent with attributes listed in reverse order, which is still valid by the protocol. This change is only for clarity.)

We discovered that PPPoATM has an excessively deep transmit queue. A queue the size of the default socket send buffer (wmem_default) is maintained between the PPP generic core and the ATM device. Fix it to queue a maximum of *two* packets. The one the ATM device is currently working on, and one more for the ATM driver to process immediately in its TX done interrupt handler. The PPP core is designed to feed packets to the channel with minimal latency, so that really ought to be enough to keep the ATM device busy. While we're at it, fix the fact that we were triggering the wakeup tasklet on *every* pppoatm_pop() call. The comment saying "this is inefficient, but doing it right is too hard" turns out to be overly pessimistic... I think :) On machines like the Traverse Geos, with a slow Geode CPU and two high-speed ADSL2+ interfaces, there were reports of extremely high CPU usage which could partly be attributed to the extra wakeups. (The wakeup handling could actually be made a whole lot easier if we stop checking sk->sk_sndbuf altogether. Given that we now only queue *two* packets ever, one wonders what the point is. As it is, you could already deadlock the thing by setting the sk_sndbuf to a value lower than the MTU of the device, and it'd just block for ever.) Signed-off-by:

This was allowing there to be cases when phonenet was not initialized and the phonet net_generic was not set for a network namespace when network device events were being reported on the netdevice_notifier for a network namespace leading to the oops above. 2) phonet_exit_net was implementing a confusing and special case of handling all network devices from going away that it was hard to see was correct, and would only occur when the phonet module was removed. Now that unregister_netdevice_notifier has been modified to synthesize unregistration events for the network devices that are extant when called this confusing special case in phonet_exit_net is no longer needed.
