vmalloc_to_page() does not work on kmalloc/kmap'd memory.
On many system kmalloc memory is not even represented in the page tables because the mapping goes through a direct bypass window.
You need to know where the object came from to convert it into a page properly. You should be allocating and passing around pages internally anyways. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
