md: rcu_read_lock() walk of mddev->disks in md_do_sync() Other walks of this list are either under rcu_read_lock() or the list mutation lock (mddev_lock()). This protects against the improbable case of a disk being removed from the array at the start of md_do_sync(). Signed-off-by: Dan Williams <dan.j.williams@intel.com>
