When we want to make drm_atomic_commit interruptible, there are a lot of places that call the lock function, which we don't have control over. Rather than trying to convert every single one, it's easier to toggle interruptible waiting per acquire_ctx. If drm_modeset_acquire_init is called with DRM_MODESET_ACQUIRE_INTERRUPTIBLE, then we will perform interruptible waits in drm_modeset_lock and drm_modeset_backoff. Changes since v1: - Fix locking example in drm_modeset_lock.c to be compatible with interruptible waiting (xexaxo) and make it default. Uninterruptible waiting shouldn't happen except in corner cases, but the example will still apply if the flag is removed. - Add drm_modeset_lock_single_interruptible() to documentation. - Fix dead link to removed drm_modeset_lock_interruptible() in drm_modeset_lock().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
