On next-20200313, running cryptsetup benchmark is stuck.
I have bisected this problem twice and the result is the same:

Since the two bisect lead to the same commit, I think it should be right one even if I dont find anything related to my problem.
But reverting this patch is impossible, so I cannot test to try without it.
