O-Subject: [RHEL-5.4 PATCH] BZ496903 Setacl not working over NFS.
Bugzilla: 496903

Hi.

Attached is a patch which address bz496903, "Setacl not working
over NFS.".  This problem described ends being due to a
miscalculation for the size of the RPC request being sent which
occurs when the NFS_ACL SETACL request is being encoded.  This
patch, from upstream, addresses that problem.

    Thanx...

       ps
