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

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

From: Chuck Lever <redacted>

commit d683cc49daf7c5afca8cd9654aaa1bf63cdf2ad9 upstream.

When encoding the NFSACL SETACL operation, reserve just the estimated
size of the ACL rather than a fixed maximum. This eliminates needless
zero padding on the wire that the server ignores.

Fixes: ee5dc7732bd5 ('NFS: Fix "kernel BUG at fs/nfs/nfs3xdr.c:1338!"')
