Hello, In the current hung_task framework, there is no way to white-list tasks for which a higher hang time out might be acceptable and expected even:
Usecase: I want to keep a low hung_task timeout to catch more tasks which are hung-up. However, certain tasks (like sync, which flushes to a slow eMMC) may have a higher timeout. Problem: There is no way to implement the aforementioned usecase without increasing the hang task timeout, which will reduce the effictiveness of the hung_task framework. Solution: 1. Introduce a white-list of tasks that have a much higher timeout. 2. Create a simple sysfs interface with which it might be possible to dynamically add/remove any task in the white-list. Please let me know what you think about the problem and the proposed solution? Regards, Aniruddha
