The following commit has been merged in the master branch: commit cb6f9fa7e45e211d3a692a3ea3ecefd6e0779d0e Author: Masahiro Yamada <yamada.masahiro(a)socionext.com> Date: Tue Sep 20 10:11:05 2016 +1000 treewide: remove redundant #include <linux/kconfig.h> Kernel source files need not include <linux/kconfig.h> explicitly because the top Makefile forces to include it with: -include $(srctree)/include/linux/kconfig.h This commit removes explicit includes except the following: * arch/s390/include/asm/facilities_src.h * tools/testing/radix-tree/linux/kernel.h These two are used for host programs.

The following commit has been merged in the master branch: commit b9838e1748e66349b6d83d3076f676d13fbb5f44 Author: Masahiro Yamada <yamada.masahiro(a)socionext.com> Date: Thu Sep 15 10:31:18 2016 +1000 treewide: remove redundant #include <linux/kconfig.h> Kernel source files need not include <linux/kconfig.h> explicitly because the top Makefile forces to include it with: -include $(srctree)/include/linux/kconfig.h This commit removes explicit includes except the following: * arch/s390/include/asm/facilities_src.h * tools/testing/radix-tree/linux/kernel.h These two are used for host programs.

[linux-next] LinuxNextTracking branch, master, updated. next-20160919

The following commit has been merged in the master branch: commit 936523441bb64cdc9a5b263e8fd2782e70313a57 Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat Aug 6 15:50:52 2016 +0200 batman-adv: Add missing refcnt for last_candidate batadv_find_router dereferences last_bonding_candidate from orig_node without making sure that it has a valid reference. This reference has to be retrieved by increasing the reference counter while holding neigh_list_lock. The lock is required to avoid that batadv_last_bonding_replace removes the current last_bonding_candidate, reduces the reference counter and maybe destroys the object in this process.
