I guess v2 is the best at the moment. I pushed a slightly modified v2 to

I think, this can be used to get a double-free from md_unregister_thread.

That is supposed to be addressed by the second one, pls consider it too.
Right, but this has not been pulled into md-next. I just wanted to note, that the current state of md-next has this problem.
If the other patch is taken, too, and works as intended, that would be solved.
[PATCH 2/2] md: protect md_unregister_thread from reentrancy
Looks good to me.
Best
