You would need a single call though, otherwise each pr_warn_once()
would have its own state that it warned once.
const char warning[] =
"======================================================\n"
"WARNING: the mand mount option is being deprecated and\n"
" will be removed in v5.15!\n"
"======================================================\n";
pr_warn_once(warning);
