Subject: [31/70] NFSv4.1: update nfs4_fattr_bitmap_maxsz

2.6.39-stable review patch.  If anyone has any objections, please let us know.

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

From: Andy Adamson <andros@...app.com>

commit e5012d1f3861d18c7f3814e757c1c3ab3741dbcd upstream.

Attribute IDs assigned in RFC 5661 now require three bitmaps.
Fixes hitting a BUG_ON in xdr_shrink_bufhead when getting ACLs.
