2020-08-24ceph: don't allow setlease on cephfsJeff Layton
Leases don't currently work correctly on kcephfs, as they are not broken when caps are revoked. They could eventually be implemented similarly to how we did them in libcephfs, but for now don't allow them.

2020-08-24RDMA/rtrs-srv: Replace device_register with device_initialize and device_addMd Haris Iqbal
There are error cases when we will call free_srv before device kobject is initialized; in such cases calling put_device generates the following warning: kobject: '(null)' (000000009f5445ed): is not initialized, yet kobject_put() is being called. So call device_initialize() only once when the server is allocated. If we end up calling put_srv() and subsequently free_srv(), our call to put_device() would result in deletion of the obj. Call device_add() later when we actually have a connection. Correspondingly, call device_del() instead of device_unregister() when srv->dev_ref falls to 0.

2020-08-24ceph: fix inode number handling on arches with 32-bit ino_tJeff Layton
Tuan and Ulrich mentioned that they were hitting a problem on s390x, which has a 32-bit ino_t value, even though it's a 64-bit arch (for historical reasons). I think the current handling of inode numbers in the ceph driver is wrong. It tries to use 32-bit inode numbers on 32-bit arches, but that's actually not a problem. 32-bit arches can deal with 64-bit inode numbers just fine when userland code is compiled with LFS support (the common case these days). What we really want to do is just use 64-bit numbers everywhere, unless someone has mounted with the ino32 mount option. In that case, we want to ensure that we hash the inode number down to something that will fit in 32 bits before presenting the value to userland. Add new helper functions that do this, and only do the conversion before presenting these values to userland in getattr and readdir. The inode table hashvalue is changed to just cast the inode number to unsigned long, as low-order bits are the most likely to vary anyway. While it's not strictly required, we do want to put something in inode->i_ino. Instead of basing it on BITS_PER_LONG, however, base it on the size of the ino_t type. NOTE: This is a user-visible change on 32-bit arches: 1/ inode numbers will be seen to have changed between kernel versions. 32-bit arches will see large inode numbers now instead of the hashed ones they saw before. 2/ any really old software not built with LFS support may start failing stat() calls with -EOVERFLOW on inode numbers >2^32. Nothing much we can do about these, but hopefully the intersection of people running such code on ceph will be very small. The workaround for both problems is to mount with "-o ino32".

2020-08-24drm/etnaviv: always start/stop scheduler in timeout processingLucas Stach
The drm scheduler currently expects that the stop/start sequence is always executed in the timeout handling, as the job at the head of the hardware execution list is always removed from the ring mirror before the driver function is called and only inserted back into the list when starting the scheduler. This adds some unnecessary overhead if the timeout handler determines that the GPU is still executing jobs normally and just wished to extend the timeout, but a better solution requires a major rearchitecture of the scheduler, which is not applicable as a fix.

2020-08-24gfs2: add some much needed cleanup for log flushes that failBob Peterson
When a log flush fails due to io errors, it signals the failure but does not clean up after itself very well. This is because buffers are added to the transaction tr_buf and tr_databuf queue, but the io error causes gfs2_log_flush to bypass the "after_commit" functions responsible for dequeueing the bd elements. If the bd elements are added to the ail list before the error, function ail_drain takes care of dequeueing them. But if they haven't gotten that far, the elements are forgotten and make the transactions unable to be freed. This patch introduces new function trans_drain which drains the bd elements from the transaction so they can be freed properly.

2020-08-23io_uring: don't recurse on tsk->sighand->siglock with signalfdJens Axboe
If an application is doing reads on signalfd, and we arm the poll handler because there's no data available, then the wakeup can recurse on the tasks sighand->siglock as the signal delivery from task_work_add() will use TWA_SIGNAL and that attempts to lock it again. We can detect the signalfd case pretty easily by comparing the poll->head wait_queue_head_t with the target task signalfd wait queue. Just use normal task wakeup for this case.

2020-08-23xhci: Always restore EP_SOFT_CLEAR_TOGGLE even if ep reset failedDing Hui
Some device drivers call libusb_clear_halt when target ep queue is not empty. (eg. spice client connected to qemu for usb redir) Before commit f5249461b504 ("xhci: Clear the host side toggle manually when endpoint is soft reset"), that works well.

2020-08-23ALSA: firewire-digi00x: exclude Avid Adrenaline from detectionTakashi Sakamoto
Avid Adrenaline is reported that ALSA firewire-digi00x driver is bound to. However, as long as he investigated, the design of this model is hardly similar to the one of Digi 00x family. It's better to exclude the model from modalias of ALSA firewire-digi00x driver.

2020-08-23ALSA; firewire-tascam: exclude Tascam FE-8 from detectionTakashi Sakamoto
Tascam FE-8 is known to support communication by asynchronous transaction only. The support can be implemented in userspace application and snd-firewire-ctl-services project has the support. However, ALSA firewire-tascam driver is bound to the model. This commit changes device entries so that the model is excluded. In a commit 53b3ffee7885 ("ALSA: firewire-tascam: change device probing processing"), I addressed to the concern that version field in configuration differs depending on installed firmware. However, as long as I checked, the version number is fixed. It's safe to return version number back to modalias.
