SO/kprobe

Kprobe based tracer

Build a kernel operations surveillant.

With this surveillant, we aim to intercept:

* kmalloc and kfree calls
* schedule calls
* up and down_interruptible calls
* mutex_lock and mutex_unlock calls

The surveillant will hold, at the process level, the number of calls for each of the above functions. For the kmalloc and kfree calls the total quantity of allocated and deallocated memory will be shown.
