Have you considered using KProbes or tracepoints ?
For KProbes you do write some kernel module to monitor the function
you want. You have to be carefull not to try to monitor inlined
functions.
You could try to combine the use of KProbes with KThreads or
usermode-helper process.
It is just a thought.
