qsp: add qsp_reset
I first implemented this by deleting all entries in the global hash table. But doing that safely slows down profiling, since we'd need to introduce rcu_read_lock/unlock in the fast path. What's implemented here avoids messing with the thread-local data in the global hash table. It achieves this by taking a snapshot of the current state, so that subsequent reports present the delta wrt to the snapshot. Signed-off-by: Emilio G.
