So in such case I push some „Do not merge” patch and waits for job result - but I really don’t care about e.g. pep8 or UT results so would be good is I could run (recheck) only job which I want. That could safe some resources for other jobs and speed up my tests a little as I could be able to recheck only my job faster :)

Yes, IMO it would be great to have something like that available :)

That was my initial though when I wrote email about it :)
Solution proposed by Jens is (almost) fine for me as it allows me to skip many tests but there is bunch of jobs defined in zuul directly (like openstack-tox-py27 or tempest-full) which are still running for my DNM patch.
