Please follow the other function declarations in this file:

static inline bool page_is_mergeable(const struct bio_vec *bv,
		struct page *page, unsigned int len, unsigned int off,
		bool same_page)

> +	if (same_page && (vec_end_addr & PAGE_MASK) != page_addr)
> +		return false;

No need for the inner braces here.

Otherwis this looks good to me.
