linux/wakelock.h

As an AI language model, I do not have access to the code repository. However, here's a brief overview of the wakelock.h header file in Linux:

The wakelock.h header file is used to define the API for managing wakelocks in the Linux kernel. A wakelock is a mechanism used to keep a device awake while it is performing a specific task. This is useful in situations where the device needs to perform a task that requires continuous CPU usage or other resources, such as network or I/O operations.

The API defined in the wakelock.h header file provides functions for acquiring and releasing wakelocks, as well as checking the current status of a wakelock. A wakelock can be acquired by calling the "wake_lock" function, and released by calling the "wake_unlock" function.

The wakelock API is commonly used in Android devices to manage power consumption and prevent unnecessary battery drain. In the Linux kernel, it is often used in drivers and other subsystems where continuous processing is required.
