Assuming you are talking about this:
https://syzkaller.appspot.com/bug?extid=a2de4763f84f61499210
It is interesting. I don't think it has anything to do with
your attempt to fix, but it certainly shows a lot of tasks that might be blocked,
one of which has rdev->mutex held while trying to acquire more locks. I do not
see an obvious deadlock, but maybe it is there.
If you decide to post more fixes for random syscaller stuff, at least link the
source material so one can take a look at the larger picture.
Thanks,
Ben
