Hi all, I ran the latest blktests (git hash: e0bb3dc05bc7) with v6.6-rc1 kernel. I observed a couple of new test case failures which are listed below. Comparing with the failures observed with v6.5 kernel [1], the failure at zbd/010 is no longer observed (#4 in [1]).

Yi Zhang observed it with linux-next kernel and reported [2]. A fix patch has been provided [3].
