Subject: [PATCH 3.2 24/87] nfsd: rename 'int access' to 'int may_flags' in
 nfsd_open()

3.2.53-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Bernd Schubert <bernd.schubert@...m.fraunhofer.de>

commit 999448a8c0202d8c41711c92385323520644527b upstream.

Just rename this variable, as the next patch will add a flag and
'access' as variable name would not be correct any more.
