Hi, > Also, how can I know by looking at the kernel code if a > function is preemptible or not ? You cannot. It is a run time property. So it is theoritically possible (although not quite likely) that one process calls the function while holding a spinlock (making it non-preemptible), and other process calls it without holding any locks (thus preemptible). At run time, ofcourse you can find out if your code is preemptible or not by looking at preempt_count.
