As the documentation for kthread_stop() says, "if threadfn() may call
do_exit() itself, the caller must ensure task_struct can't go away".
dm-crypt does not ensure this and therefore crashes when crypt_dtr()
calls kthread_stop(). The crash is trivially reproducible by adding

Hi guys,
I'm sorry if someone else has already asked the same question before, but

Change dm-flakey to implement direct_access function,
flakey_direct_access(), which maps sector and calls direct_access
function of its physical target device. This pretty much is a copy
from DM Linear.
This allows fs with DAX to pass in xfstests. It does not actually introduce
data corruption and

the length should be MPATH_MX_TIDS*sizeof(struct transportid).
