I'd just use pr_fmt_warn.
Instead of all this other extra stuff:
What did you think of avoiding all of this and
having __dynamic_pr_debug move the fmt pointer over
any initial KBUILD_MODULE ": "
int __dynamic_pr_debug(struct _ddebug *descriptor, const char *fmt, ...)
{
[...]
size_t modsize = strlen(descriptor->modname);
if (0 == strncmp(fmt, descriptor->modname, modsize) &&
0 == strncmp(fmt + modsize, ": ", 2))
fmt += modsize + 2;
vprintk(fmt, ...)
?
