Add some simple wrappers around incrementing/decrementing kthread_work.cancelling under lock, along with checking whether queuing is currently allowed on a given kthread_work, which we'll use want to implement work cancelling with DRM's vblank work helpers.

Switch the function documentation to kerneldoc comments, and add WARN_ON_ONCE asserts that the calling thread is a kernel thread and does not have ->mm set (or has ->mm set in the case of unuse_mm). Also give the functions a kthread_ prefix to better document the use case.

Hi all, this series improves the use_mm / unuse_mm interface by better documenting the assumptions, and my taking the set_fs manipulations spread over the callers into the core API. Changes since v1: - drop a few patches - fix a comment typo - cover the newly merged use_mm/unuse_mm caller in vfio

Nvidia released some documentation on how CRC support works on their GPUs, hooray! So: this patch series implements said CRC support in nouveau, along with adding some special debugfs interfaces for some relevant igt-gpu-tools tests (already on the ML). First - we add some new functionality to kthread_work in the kernel, and then use this to add a new feature to DRM that Ville Syrj?l? came up with: vblank workers. Basically, this is just a generic DRM interface that allows for scheduling high-priority workers that start on a given vblank interrupt. Note that while we're currently only using t...
