Subject: [140/244] Fix the conflict between rwpidforward and rw mount options
3.0-stable review patch. If anyone has any objections, please let us know.
------------------
From: Steve French <sfrench@...ibm.com>
commit c9c7fa0064f4afe1d040e72f24c2256dd8ac402d upstream.
Both these options are started with "rw" - that's why the first one
isn't switched on even if it is specified. Fix this by adding a length
check for "rw" option check.
