Hi,<div><br></div><div>Is there any way to call a function defined in a kernel module from within the kernel proper?</div><div><br></div><div>Here&#39;s what I&#39;m trying to do:</div><div><br></div><div>I&#39;m trying to keep track of when and for how long a process is being executed on the processor, i.e. I need to know when context switches occur.</div>
<div><br></div><div>There is a function called context_switch() in linux/kernel/sched/core.c that is called whenever a context switch happens. I would like to call a function in a kernel module I&#39;ve written from within context_switch() and pass some data to it.</div>
<div><br></div><div>I&#39;ve seen how to communicate between user space and kernel space, such as using a file in /dev or using system calls, but not how to communicate within the kernel itself.</div><div><br></div><div>Regards,</div>
