I'm thinking it is cleaner to have two helper functions and have them
both return bool.

static __always_inline bool str_has_prefix(const char *str, const char *prefix)
{
	return !strncmp(str, prefix, strlen(prefix));
}

( I still like to keep the __always_inline, it doesn't hurt )

And I'll make a separate patch that adds:

static __always_inline bool
str_has_prefix_len(const char *str, const char *prefix, unsigned int *len)
{
	*len = strlen(prefix);
	return !strncmp(str, prefix, *len) ? *len : 0;
}

Everyone OK with that?
