    itimers: Add tracepoints for itimer · 3f0a525e
    Xiao Guangrong authored
    Add tracepoints for all itimer variants: ITIMER_REAL, ITIMER_VIRTUAL
    and ITIMER_PROF.
    
    [ tglx: Fixed comments and made the output more readable, parseable
      	and consistent. Replaced pid_vnr by pid_nr because the hrtimer
      	callback can happen in any namespace ]
