2015-09-17ieee802154: 6lowpan: remove EXPORT_SYMBOLAlexander Aring
This function is used internally inside of ieee802154 6lowpan module only and not outside of any other module. We don't need to export this function then.

2015-09-17ieee802154: 6lowpan: register packet layer while openAlexander Aring
This patch moves the open count handling while doing open of a lowpan interface. We need the packet handler register at first when one lowpan interface is up. There exists a small case when all lowpan interfaces are down and the 802154 packet layer is still registered. To reduce some overhead we will register the packet layer when the first lowpan interface comes up and unregister when the last interface will become down.

2015-09-17ieee802154: 6lowpan: change dev vars to wdev and ldevAlexander Aring
Inside the IEEE 802.15.4 6LoWPAN subsystem we use two interfaces which are wpan and lowpan interfaces. Instead of using always the variable name "dev" for both we rename the "dev" variable to wdev which means the wpan net_device and ldev which means a lowpan net_device. This avoids confusing and always looking back to see which net_device is meant by the variable name "dev".

2015-09-17Bluetooth: btmrvl: skb resource leak, and double free.Kieran Bingham
if btmrvl_tx_pkt() is called, and the branch if (skb_headroom(skb) < BTM_HEADER_LEN) evaluates positive, a new skb is allocated via skb_realloc_headroom. The original skb is stored in a tmp variable, before being free'd. However on success, the new skb, is not free'd, nor is it returned to the caller which will then double-free the original skb. This issue exists from the original driver submission in commit: #132ff4e5fa8dfb71a7d99902f88043113947e972 If this code path had been alive, it would have been noted from the double-free causing a panic. All skb's here should be allocated through bt_skb_alloc which adds 8 bytes as headroom, which is plenty against the 4 bytes pushed on by this driver. This code path is dead, and buggy at the same time, so the cleanest approach is to remove the affected branch.

2015-09-17Bluetooth: close HCI device when user channel socket gets closedSimon Fels
With 9380f9eacfbbee701daa416edd6625efcd3e29e1 the order of unsetting the HCI_USER_CHANNEL flag of the HCI device was reverted to ensure the device is first closed before making it available again. Due to hci_dev_close checking for HCI_USER_CHANNEL being set on the device it was never really closed and was kept opened. We're now calling hci_dev_do_close directly to make sure the device is correctly closed and we keep the correct order to unset the flag on our device object.

2015-09-15rtnetlink: RTEXT_FILTER_SKIP_STATS support to avoid dumping inet/inet6 statsSowmini Varadhan
Many commonly used functions like getifaddrs() invoke RTM_GETLINK to dump the interface information, and do not need the the AF_INET6 statististics that are always returned by default from rtnl_fill_ifinfo(). Computing the statistics can be an expensive operation that impacts scaling, so it is desirable to avoid this if the information is not needed. This patch adds a the RTEXT_FILTER_SKIP_STATS extended info flag that can be passed with netlink_request() to avoid statistics computation for the ifinfo path.

2015-09-15drivers: net: cpsw: Add support to drive gpios for ethernet to be functionalMugunthan V N
In DRA72x EVM, by default slave 1 is connected to the onboard phy, but slave 2 pins are also muxed with video input module which is controlled by pcf857x gpio and currently to select slave 0 to connect to phy gpio hogging is used, but with omap2plus_defconfig the pcf857x gpio is built as module. So when using NFS on DRA72x EVM, board doesn't boot as gpio hogging do not set proper gpio state to connect slave 0 to phy as it is built as module and you do not see any errors for not setting gpio and just mentions dhcp reply not got. To solve this issue, introducing "mode-gpios" in DT when gpio based muxing is required. This will throw a warning when gpio get fails and returns probe defer. When gpio-pcf857x module is installed, cpsw probes again and ethernet becomes functional. Verified this on DRA72x with pcf as module and ramdisk.

Pull blk-cg updates from Jens Axboe: "A bit later in the cycle, but this has been in the block tree for a a while. This is basically four patchsets from Tejun, that improve our buffered cgroup writeback. It was dependent on the other cgroup changes, but they went in earlier in this cycle. Series 1 is set of 5 patches that has cgroup writeback updates: - bdi_writeback iteration fix which could lead to some wb's being skipped or repeated during e.g. sync under memory pressure. - Simplification of wb work wait mechanism. - Writeback tracepoints updated to report cgroup. Series 2 is is a set of updates for the CFQ cgroup writeback handling: cfq has always charged all async IOs to the root cgroup. It didn't have much choice as writeback didn't know about cgroups and there was no way to tell who to blame for a given writeback IO. writeback finally grew support for cgroups and now tags each writeback IO with the appropriate cgroup to charge it against. This patchset updates cfq so that it follows the blkcg each bio is tagged with. Async cfq_queues are now shared across cfq_group, which is per-cgroup, instead of per-request_queue cfq_data. This makes all IOs follow the weight based IO resource distribution implemented by cfq. - Switched from GFP_ATOMIC to GFP_NOWAIT as suggested by Jeff. - Other misc review points addressed, acks added and rebased. Series 3 is the blkcg policy cleanup patches: This patchset contains assorted cleanups for blkcg_policy methods and blk[c]g_policy_data handling. - alloc/free added for blkg_policy_data. exit dropped. - alloc/free added for blkcg_policy_data. - blk-throttle's async percpu allocation is replaced with direct allocation. - all methods now take blk[c]g_policy_data instead of blkcg_gq or blkcg. And finally, series 4 is a set of patches cleaning up the blkcg stats handling: blkcg's stats have always been somwhat of a mess. This patchset tries to improve the situation a bit. - The following patches added to consolidate blkcg entry point and blkg creation. This is in itself is an improvement and helps colllecting common stats on bio issue. - per-blkg stats now accounted on bio issue rather than request completion so that bio based and request based drivers can behave the same way. The issue was spotted by Vivek. - cfq-iosched implements custom recursive stats and blk-throttle implements custom per-cpu stats. This patchset make blkcg core support both by default. - cfq-iosched and blk-throttle keep track of the same stats multiple times.
