Improve strace output of various syscalls which either have none
or only int-type parameters.

It would be nice if you included a history of the patch (after the line
"---", as it is customary for single patch submission). You changed
only ioctl() in v2, right?

Yes. Will add history in next round.

I missed your v2, but responded with several hints to v1.

Yes, I saw all your mails.
Thanks for your feedback!

userfaultfd(), membarrier(), mlock2()... - all could be included into
your patch.

I think there are quite some more which I didn't included.
That's why I wrote "*various*" and not "*all*" in my changelog.
I'm debugging other code, and the ones I fixed are the ones I
actually tested with my code.

If you don't have handy way to test the other syscalls, I'll rather restrict your patch to the one you tested, at least you are certain you didn't introduced regressions. Unless their implementation is trivial, of course.
