[patch V2 04/38] posix-cpu-timers: Provide quick sample function for itimer

get_itimer() needs a sample of the current thread group cputime. It invokes thread_group_cputimer() - which is a misnomer. That function also starts eventually the group cputime accouting which is bogus because the accounting is already active when a timer is armed. Signed-off-by: Thomas Gleixner
