Implement arch specific arch_get_memory_phys_device function and initialize phys_device for each memory section. That way we finally can tell which piece of memory belongs to which physical device. This makes s390's /sys/devices/system/memory/memoryX/phys_device display the correct thing? Signed-off-by:

/sys/devices/system/memory/memoryX/phys_device is supposed to contain the number of the physical device that the corresponding piece of memory belongs to. In case a physical device should be replaced or taken offline for whatever reason it is necessary to set all corresponding memory pieces offline. The current implementation always sets phys_device to '0' and there is no way or hook to change that. Seems like there was a plan to implement that but it wasn't finished for whatever reason. So add a weak function which architectures can override to actually set the phys_device from within add_memory_block(). Signed-off-by:

jffs2 uses rb_node = NULL; to zero rb_root. The problem with this is that 17d9ddc72fb8bba0d4f678 ("rbtree: Add support for augmented rbtrees") in the linux-next tree adds a new field to that struct which needs to be NULL as well. This patch uses RB_ROOT as the intializer so all of the relevant fields will be NULL'd. Signed-off-by:Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Cc: Eric Paris <eparis@redhat.com> Acked-by:

Without CONFIG_BRIDGE_IGMP_SNOOPING, BR_INPUT_SKB_CB(skb)->mrouters_only is not appropriately initialized, so we can see garbage. A clear option to fix this is to set it even without that config, but we cannot optimize out the branch. Let's introduce a macro that returns value of mrouters_only and let it return 0 without CONFIG_BRIDGE_IGMP_SNOOPING. Signed-off-by:

Its a straightforward inversion, tipc_ref_acquire takes two locks in this order: ref_table_lock entry->lock while tipc_deleteport takes them in this order: entry->lock (via tipc_port_lock()) ref_table_lock (via tipc_ref_discard()) when the same entry is referenced, we get the above warning. The fix is equally straightforward. Theres no real relation between the entry->lock and the ref_table_lock (they just are needed at the same time), so move the entry->lock aquisition in tipc_ref_acquire down, after we unlock ref_table_lock (this is safe since the ref_table_lock guards changes to the reference table, and we've already claimed a slot there. I've tested the below fix and confirmed that it clears up the lockdep issue Signed-off-by: -

This patch fixes UDP socket refcnt bugs in the pppol2tp driver. A bug can cause a kernel stack trace when a tunnel socket is closed. A way to reproduce the issue is to prepare the UDP socket for L2TP (by opening a tunnel pppol2tp socket) and then close it before any L2TP sessions are added to it. The sequence is Create UDP socket Create tunnel pppol2tp socket to prepare UDP socket for L2TP pppol2tp_connect: session_id=0, peer_session_id=0 L2TP SCCRP control frame received (tunnel_id==0) pppol2tp_recv_core: sock_hold() pppol2tp_recv_core: sock_put L2TP ZLB control frame received (tunnel_id=nnn) pppol2tp_recv_core: sock_hold() pppol2tp_recv_core: sock_put Close tunnel management socket pppol2tp_release: session_id=0, peer_session_id=0 Close UDP socket udp_lib_close: BUG The addition of sock_hold() in pppol2tp_connect() solves the problem. For data frames, two sock_put() calls were added to plug a refcnt leak per received data frame. The ref that is grabbed at the top of pppol2tp_recv_core() must always be released, but this wasn't done for accepted data frames or data frames discarded because of bad UDP checksums. This leak meant that any UDP socket that had passed L2TP data traffic (i.e. L2TP data frames, not just L2TP control frames) using pppol2tp would not be released by the kernel.

When transmitting L2TP frames, we derive the outgoing interface's UDP checksum hardware assist capabilities from the tunnel dst dev. This can sometimes be NULL, especially when routing protocols are used and routing changes occur.

Re-apply a commit that had been reverted due to regressions that have since been fixed. Original commit: d2859751 Author: Nick Piggin <npiggin@suse.de> Date: Tue, 6 Jan 2009 14:40:44 +1100 XFS's vmap batching simply defers a number (up to 64) of vunmaps, and keeps track of them in a list. To purge the batch, it just goes through the list and calls vunamp on each one. This is pretty poor: a global TLB flush is generally still performed on each vunmap, with the most expensive parts of the operation being the broadcast IPIs and locking involved in the SMP callouts, and the locking involved in the vmap management -- none of these are avoided by just batching up the calls. I'm actually surprised it ever made much difference. (Now that the lazy vmap allocator is upstream, this description is not quite right, but the vunmap batching still doesn't seem to do much). Rip all this logic out of XFS completely. I will improve vmap performance and scalability directly in subsequent patch. Signed-off-by: -

If we were to dynamically register/unregister leds and have udev or other daemons handle the leds class uevents, we would be notified of the adding of a new LED and if the daemon immediately tries to open one of the attributes of the led device, it would fail with a "no such file or directory" error since this the attributes are not yet created. Fix this by switching attributes to be class-wide, such that the driver core will register these attributes with device_add_attrs and then emit the kobject_uevent ADD signal. Signed-off-by:

The driver wrongly sets default state for LEDs that don't specify default-state property. Currently the driver handles default state this way: memset(&led, 0, sizeof(led)); for_each_child_of_node(np, child) { state = of_get_property(child, "default-state", NULL); if (state) { if (!strcmp(state, "keep")) led.default_state = LEDS_GPIO_DEFSTATE_KEEP; ... } ret = create_gpio_led(&led, ...); } Which means that all LEDs that do not specify default-state will inherit the last value of the default-state property, which is wrong. This patch fixes the issue by moving LED's template initialization into the loop body. Signed-off-by:Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by:

This patch adds an LED driver to support the Dell Activity LED on the Dell Latitude 2100 netbook and future products to come. The Activity LED is visible externally in the lid so classroom instructors can observe it from a distance. The driver uses the sysfs led_class and provides a standard LED interface.

Remove the need for "depends on LEDS_CLASS" by wrapping the affected config options in an if/endif block. Similar for "depends on LEDS_TRIGGERS". LEDS_COBALT_RAQ still has a "depends on LEDS_CLASS=y" since it cannot be selected to build as a module. Signed-off-by:
