[PATCH] cgroup: fix display of forceidle time at root

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


We need to reset forceidle_sum to 0 when reading from root, since the
bstat we accumulate into is stack allocated.

To make this more robust, just replace the existing cputime reset with a
memset of the overall bstat.
