Hi all, I have to develop some real-time code. I need to execute some code *any* time the executing task changes. I already tried to put a hook in the __schedule() function, before the call to the context_switch() function. However, my code is called two consecutive times with the same prev or the same next: seems that between two consecutive calls someone has changed the executing task... Can somebody please tell me where exactly I should put my hook ?? Many thanks, Claudio Scordino -- Kernelnewbies: Help each other learn about the Linux kernel.
