------------------------------------------------------
Subject: tmpfs: mpol=bind:0 don't cause mount error.
From: KOSAKI Motohiro <kosaki.motohiro@xxxxxxxxxxxxxx>
Currently, following mount operation cause mount error.
% mount -t tmpfs -ompol=bind:0 none /tmp
Because commit 71fe804b6d5 (mempolicy: use struct mempolicy pointer in
shmem_sb_info) corrupted MPOL_BIND parse code.
This patch restore the needed one.
