2020-02-11ALSA: usb-audio: Apply sample rate quirk for Audioengine D1Arvind Sankar
The Audioengine D1 (0x2912:0x30c8) does support reading the sample rate, but it returns the rate in byte-reversed order. When setting sampling rate, the driver produces these warning messages: [168840.944226] usb 3-2.2: current rate 4500480 is different from the runtime rate 44100 [168854.930414] usb 3-2.2: current rate 8436480 is different from the runtime rate 48000 [168905.185825] usb 3-2.1.2: current rate 30465 is different from the runtime rate 96000 As can be seen from the hexadecimal conversion, the current rate read back is byte-reversed from the rate that was set. 44100 == 0x00ac44, 4500480 == 0x44ac00 48000 == 0x00bb80, 8436480 == 0x80bb00 96000 == 0x017700, 30465 == 0x007701 Rather than implementing a new quirk to reverse the order, just skip checking the rate to avoid spamming the log.

Accidentally removed the 'ret=0' initialization, and thus we're potentially looking at some stack garbage here.

2020-02-11drm/i915: Disable use of hwsp_cacheline for kernel_contextChris Wilson
Currently on execlists, we use a local hwsp for the kernel_context, rather than the engine's HWSP, as this is the default for execlists. However, seqno wrap requires allocating a new HWSP cacheline, and may require pinning a new HWSP page in the GGTT. This operation requiring pinning in the GGTT is not allowed within the kernel_context timeline, as doing so may require re-entering the kernel_context in order to evict from the GGTT. As we want to avoid requiring a new HWSP for the kernel_context, we can use the permanently pinned engine's HWSP instead. However to do so we must prevent the use of semaphores reading the kernel_context's HWSP, as the use of semaphores do not support rollover onto the same cacheline. Fortunately, the kernel_context is mostly isolated, so unlikely to give benefit to semaphores.

2020-02-11drm/irq: remove check on dev->dev_privateJani Nikula
There is no real reason to require drivers to set and use dev->dev_private. Indeed, the current recommendation, as documented in drm_device.h, is to embed struct drm_device in the per-device struct instead of using dev_private. Remove the requirement for dev_private to have been set to indicate driver initialization. For background, quoting Daniel Vetter: Now there might be some hilarious races this papers over, but: - Proper drivers should only call drm_dev_register once everything is set up, including this stuff here. No race possible with anything else really. - Slightly more wobbly drivers, including the legacy ones, all use drm_global_mutex. This was the former BKL, which means that it was impossible for soeone to go through the load/unload/reload (between lastclose and firstopen) paths and also run the ioctl. But the ioctl had to be made unlocked because blocking there killed X: commit 8f4ff2b06afcd6f151868474a432c603057eaf56 Author: Ilija Hadzic <ihadzic@research.bell-labs.com> Date: Mon Oct 31 17:46:18 2011 -0400 drm: do not sleep on vblank while holding a mutex The even more legacy DRM_CONTROL ioctl stayed fully locked. But the file open/close paths are still fully locked, and that's the only place legacy drivers should call drm_irq_install/uninstall, so should all still be fully ordered and protected and happy.

2020-02-11ALSA: usb-audio: Fix UAC2/3 effect unit parsingTakashi Iwai
We've got a regression report about M-Audio Fast Track C400 device, and the git bisection resulted in the commit e0ccdef92653 ("ALSA: usb-audio: Clean up check_input_term()"). This commit was about the rewrite of the input terminal parser, and it's not too obvious from the change what really broke. The answer is: it's the interpretation of UAC2/3 effect units. In the original code, UAC2 effect unit is as if through UAC1 processing unit because both UAC1 PU and UAC2/3 EU share the same number (0x07). The old code went through a complex switch-case fallthrough, finally bailing out in the middle: if (protocol == UAC_VERSION_2 && hdr[2] == UAC2_EFFECT_UNIT) { /* UAC2/UAC1 unit IDs overlap here in an * uncompatible way. Ignore this unit for now. */ return 0; } ... and this special handling was missing in the new code; the new code treats UAC2/3 effect unit as if it were equivalent with the processing unit. Actually, the old code was too confusing. The effect unit has an incompatible unit description with the processing unit, so we shouldn't have dealt with EU in the same way. This patch addresses the regression by changing the effect unit handling to the own parser function. The own parser function makes the clear distinct with PU, so it improves the readability, too. The EU parser just sets the type and the id like the old kernels. Once when the proper effect unit support is added, we can revisit this parser function, but for now, let's keep this simple setup as is.

2020-02-11ceph: noacl mount option is effectively ignoredXiubo Li
For the old mount API, the module parameters parseing function will be called in ceph_mount() and also just after the default posix acl flag set, so we can control to enable/disable it via the mount option. But for the new mount API, it will call the module parameters parseing function before ceph_get_tree(), so the posix acl will always be enabled.

2020-02-11ceph: canonicalize server path in placeIlya Dryomov
syzbot reported that 4fbc0c711b24 ("ceph: remove the extra slashes in the server path") had caused a regression where an allocation could be done under a spinlock -- compare_mount_options() is called by sget_fc() with sb_lock held. We don't really need the supplied server path, so canonicalize it in place and compare it directly. To make this work, the leading slash is kept around and the logic in ceph_real_mount() to skip it is restored. CEPH_MSG_CLIENT_SESSION now reports the same (i.e. canonicalized) path, with the leading slash of course.

In O_APPEND & O_DIRECT mode, the data from different writers will be possibly overlapping each other since they take the shared lock.
