struct queue* bt_gatt_client::long_write_queue

Queue of long write requests. An error during "prepare write" requests can result in a cancel through "execute write". To prevent cancellation of prepared writes to the wrong attribute and multiple requests to the same attribute that may result in a corrupted final value, we avoid interleaving prepared writes.
