This creates a circular\nlock dependency with configfs_rmdir():\n\n  dep_lock -\u003e configfs root inode lock -\u003e su_mutex -\u003e dep_lock\n\nIn usbg_make_tpg(), dep_lock only serialized the read of opts-\u003eready,\nwhich is a monotonic flag that transitions from false to true exactly\nonce (in tcm_set_name()) and never reverts.
