Hi,
I am just a beginner. I have tried procfs, Netlink socket to communicate between user space and kernel space and it works fine.
I am developing a monitoring utility to trace the VFS operation and find the frequency of VFS function calls. This monitoring utility runs in kernel space. We have to record the occurrence of each VFS function calls (like vfs_open(), vfs_read()). I don't know which is best mechanism to report this VFS event to the monitoring utility.
Could anyone please suggest the best mechanism to transfer data frequently between kernel modules.
Thank you!

What have you tried that did not work out?

This feels like a homework question to me, are you sure you are not just
asking for us to do your work for you? :)
thanks,
