[PATCH 08/12] hrtimer: completely remove it_real_value

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Remove the it_real_value from /proc/*/stat, during 1.2.x was the last
time it returned useful data (as it was directly maintained by the
scheduler), now it's only a waste of time to calculate it.
