The current formatting doesn't quite work with kernel-doc.

- * 	This function allocates a page from the kernel page pool and applies
- *	a NUMA policy associated with the VMA or the current process.
- *	When VMA is not NULL caller must read-lock the mmap_lock of the
- *	mm_struct of the VMA to prevent it from going away. Should be used for
- *	all allocations for pages that will be mapped into user space. Returns
- *	NULL when no page can be allocated.
+ * Return: The page on success or NULL if allocation fails.
