using a "-M" option on cyclictest defeats the "-D 30" option

using a "-M" option on cyclictest defeats the "-D 30" option

[Gautam Thaker]

I have noticed that

sudo time ./cyclictest -S -D 30

properly completes the test and exits in 30 seconds. However,

doing:

sudo time ./cyclictest -S -D 30 -M

the test never stops, I have to control-C out of it. Is this intended
behavior? The man page did not say anything about this. I would like
to use both -D <many_hours>   and -M together.

Thanks for any comments.

It works for v2.2. What version do you have? I tested it with 5 secs but
I would expect that it behaves the same way for 30 secs.

My apologies. I was using "cyclictest" from git repository:

node-0> git remote -vv
origin git://git.kernel.org/pub/scm/utils/rt-tests/rt-tests.git (fetch)
origin git://git.kernel.org/pub/scm/utils/rt-tests/rt-tests.git (push)

And I was on stable/1.0   branch!!  (I had thought pointing to repo in
kernel.org I would be current, but I should have checked.)

I compiled version 2.3  (tip of "main" branch) and it works as expected.
