For the replace tests we need a device as a spare device, here functions _spare_dev_get() and _spare_dev_put() will get it from the SCRATCH_DEV_POOL_SAVED, which is set when _scratch_dev_pool_get() is called, and is based on how many has already been assigned to SCRATCH_DEV_POOL. usage: _scratch_dev_pool_get 3 _spare_dev_get SPARE_DEV will have a device set which can be used as the replace target device. _spare_dev_put _scratch_dev_pool_put _spare_dev_get() will pick the next device after SCRATCH_DEV_POOL devices, from the SCRATCH_DEV_POOL_SAVED, and assigns it to SPARE_DEV. _spare_dev_put() will set to SPARE_DEV to null.
