Hans Verkuil 8ab75e3ecd [media] v4l2-dev: make it possible to skip locking for selected ioctls ... Using the V4L2 core lock is a very robust method that is usually very good at doing the right thing. But some drivers, particularly USB drivers, may want to prevent the core from taking the lock for specific ioctls, particularly buffer queuing ioctls. The reason is that certain commands like S_CTRL can take a long time to process over USB and all the time the core has the lock, preventing VIDIOC_DQBUF from proceeding, even though a frame may be ready in the queue. This introduces unwanted latency. Since the buffer queuing commands often have their own internal lock it is often not necessary to take the core lock. Drivers can now say that they don't want the core to take the lock for specific ioctls. As it is a specific opt-out it makes it clear to the reviewer that those ioctls will need more care when reviewing.
