2016-12-06drm/amdgpu: don't add files at control minor debugfs directoryNicolai Stange
Since commit 8a357d10043c ("drm: Nerf DRM_CONTROL nodes"), a struct drm_device's ->control member is always NULL. In the case of CONFIG_DEBUG_FS=y, amdgpu_debugfs_add_files() accesses ->control->debugfs_root though. This results in a NULL pointer dereference. Fix this by omitting the drm_debugfs_create_files() call for the control minor debugfs directory which is now non-existent anyway.

2016-12-06perf/x86: Fix full width counter, counter overflowPeter Zijlstra (Intel)
Lukasz reported that perf stat counters overflow handling is broken on KNL/SLM. Both these parts have full_width_write set, and that does indeed have a problem. In order to deal with counter wrap, we must sample the counter at at least half the counter period (see also the sampling theorem) such that we can unambiguously reconstruct the count. However commit: 069e0c3c4058 ("perf/x86/intel: Support full width counting") sets the sampling interval to the full period, not half. Fixing that exposes another issue, in that we must not sign extend the delta value when we shift it right; the counter cannot have decremented after all. With both these issues fixed, counter overflow functions correctly again.

2016-12-06nvmet: Fix possible infinite loop triggered on hot namespace removalSolganik Alexander
When removing a namespace we delete it from the subsystem namespaces list with list_del_init which allows us to know if it is enabled or not. The problem is that list_del_init initialize the list next and does not respect the RCU list-traversal we do on the IO path for locating a namespace. Instead we need to use list_del_rcu which is allowed to run concurrently with the _rcu list-traversal primitives (keeps list next intact) and guarantees concurrent nvmet_find_naespace forward progress. By changing that, we cannot rely on ns->dev_link for knowing if the namspace is enabled, so add enabled indicator entry to nvmet_ns for that.

vhci_hcd calls sysfs_create_group() with dynamically allocated sysfs attributes triggering the lock-class key not persistent warning. Call sysfs_attr_init() for dynamically allocated sysfs attributes to fix it. vhci_hcd vhci_hcd: USB/IP Virtual Host Controller vhci_hcd vhci_hcd: new USB bus registered, assigned bus number 2 BUG: key ffff88006a7e8d18 not in .data! ------------[ cut here ]------------ WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:3131 lockdep_init_map+0x60c/0x770 DEBUG_LOCKS_WARN_ON(1)[ 1.567044] Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.9.0-rc7+ #58 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Bochs 01/01/2011 ffff88006bce6eb8 ffffffff81f96c8a ffffffff00000a02 1ffff1000d79cd6a ffffed000d79cd62 000000046bce6ed8 0000000041b58ab3 ffffffff8598af40 ffffffff81f969f8 0000000000000000 0000000041b58ab3 0000000000000200 Call Trace: [< inline >] __dump_stack lib/dump_stack.c:15 [<ffffffff81f96c8a>] dump_stack+0x292/0x398 lib/dump_stack.c:51 [<ffffffff812b808f>] __warn+0x19f/0x1e0 kernel/panic.c:550 [<ffffffff812b8195>] warn_slowpath_fmt+0xc5/0x110 kernel/panic.c:565 [<ffffffff813f3efc>] lockdep_init_map+0x60c/0x770 kernel/locking/lockdep.c:3131 [<ffffffff819e43d4>] __kernfs_create_file+0x114/0x2a0 fs/kernfs/file.c:954 [<ffffffff819e68f5>] sysfs_add_file_mode_ns+0x225/0x520 fs/sysfs/file.c:305 [< inline >] create_files fs/sysfs/group.c:64 [<ffffffff819e8a89>] internal_create_group+0x239/0x8f0 fs/sysfs/group.c:134 [<ffffffff819e915f>] sysfs_create_group+0x1f/0x30 fs/sysfs/group.c:156 [<ffffffff8323de24>] vhci_start+0x5b4/0x7a0 drivers/usb/usbip/vhci_hcd.c:978 [<ffffffff82c907ca>] usb_add_hcd+0x8da/0x1c60 drivers/usb/core/hcd.c:2867 [<ffffffff8323bc57>] vhci_hcd_probe+0x97/0x130 drivers/usb/usbip/vhci_hcd.c:1103 --- --- ---[ end trace c33c7b202cf3aac8 ]--- Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com> Reported-by: Andrey Konovalov <andreyknvl@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-12-06usb: core: usbport: Use proper LED API to fix potential crashRafał Miłecki
Calling brightness_set manually isn't safe as some LED drivers don't implement this callback. The best idea is to just use a proper helper which will fallback to the brightness_set_blocking callback if needed.
