HI !
minor change request to the histogram in cyclictest to record the
comandline - needed for confused people like me ...
I would prefere if the commandline with the parameters used during the
test-run would be recorded in the histogram output - thats what the
below patch does. i.e. runing:
hofrat@debian:~/rt-tests$ ./cyclictest -q -p 10 -n -h 50 -l 1000
would result in the histogram begin displayed as
# cmdline: ./cyclictest -q -p 10 -n -h 50 -l 1000
# Histogram
000000 000000
000001 000000
000002 000000
...
thx!
hofrat
