Subject: [PATCH 0/2] tracing: Add trace for task_exit


Patch 1 adds a tracepoint for task_exit and use trace strings for that.
the second algin the other (task_newtask and task_rename) to use same
string.

Knowing when and why tasks dies are very useful for varius debugging
aktivites in userspace and we can trace tasks complete life-cycle.
