[sashiko-bot at kernel.org]

> ipe_bdev_setintegrity() frees the old root hash when dm-verity publishes
> a new one on ->preresume, while policy evaluation can still be
> dereferencing it.
> 
> Protect the root hash with RCU. The evaluation path already runs under
> rcu_read_lock().
> 
> Fixes: e155858dd995 ("ipe: add support for dm-verity as a trust provider")
