4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Peng Tao <[email protected]> commit 048883e0b934d9a5103d40e209cb14b7f33d2933 upstream. We really want sizeof(struct page *) instead. Otherwise we limit maximum IO size to 64 pages rather than 512 pages on a 64bit system. Fixes 2e11f829(nfs: cap request size to fit a kmalloced page array).
