strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. data_page wants to be NUL-terminated and NUL-padded, use strscpy_pad to provide both of these. data_page no longer awkwardly relies on init_mount to perform its NUL-termination, although that sanity check is left unchanged.
