An example use case is a laptop, whose keyboard can be folded under the screen to create tablet-like experience. The user then must hold the laptop in such a way that it is difficult to avoid pressing the keyboard keys. It is therefore desirable to temporarily disregard input from the keyboard, until it is folded back. This obviously is a policy which should be kept out of the kernel, but the kernel must provide suitable means to implement such a policy. Due to interactions with suspend/resume, a helper has been added for drivers to decide if the device is being used or not (PATCH 1/7) and it has been applied to relevant drivers (PATCH 2-5/7). Patches 2-5 are only being sent to relevant mailing lists and maintainers. PATCH 6/7 adds support for inhibiting input devices, while PATCH 7/7 provides an example how to convert a driver to take advantage of this new feature. Patch 7/7 is only being sent to input mailing list and maintainer.
