| | | | | | | | | | | | | | | Don't miss latency which exceed the histogram limit - instead sample limit exceeding latency in the last bucket. This is a leftover from cyclictest_histogram.patch: -> Todo: Currently cyclictest does not report the number of samples -> that exceeded the histogram max latency. Handle OOM.

* Avoid segfault of cyclictest if it gets immediately interrupted.Daniel Gollub2009-07-021-5/+12
| | | | | | | | | | | | | | | | | | | | | If clock_nanosleep() gets interrupted this could result in a negative time diff from calcdiff(). With the histogram patch this leads to a segfault, since the time diff is used as index for the histogram array: Core was generated by `/usr/bin/cyclictest -n -q -p 99 -t 2 -i 500 -l 1000000 -h 20000'.
