Close the race window in zvol_open() to prevent removal of zvol_state in the 'first open' code path. Move the call to check_disk_change() under zvol_state_lock to make sure the zvol_media_changed() and zvol_revalidate_disk() called by check_disk_change() are invoked with positive zv_open_count. Skip opened zvols when removing minors and set private_data to NULL for zvols that are not in use whose minors are being removed, to indicate to zvol_open() that the state is gone. Skip opened zvols when renaming minors to avoid modifying zv_name that might be in use, e.g. in zvol_ioctl(). Drop zvol_state_lock before calling add_disk() when creating minors to avoid deadlocks with zvol_open(). Wrap dmu_objset_find() with spl_fstran_mark()/unmark().
