It looks like on 5.18-rc1+ blktest is not running for me. (Last time I ran it was pre 5.18)
I am not seeing the Warning but instead it just hangs? Are you enabling some lock checking
that I am not? If so how?


Hi Bob,

The warning shown in the email at the start of this thread has beenreported by lockdep. I think that you will need to enable at least thefollowing in the kernel configuration:


CONFIG_LOCKDEP=y
CONFIG_PROVE_LOCKING=y

Thanks,

Bart.
