Hi list,
When reading the kernel codes, I get confused about the following questions:
1. Within the struct __wait_queue, there is a pointer "wait_queue_func_t". Is it true that in most cases it is pointed to "default_wake_function" ?
2. The "default_wake_function" actually wake up the current task by invoking "try_to_wake_up". I create a simple wait_queque like structure, with only a spin_lock, a task pointer and a list head. Then the question is can I wake up a task in such a simple wait queue by simply doing something like "current->state = TASK_RUNNING" and remove the task from the queue?
Maybe the questions are naive or even not good questions, but any hint will be really appreciated.
TIA
justin
