From 8340437210390676f687633a80e3748c40885dc8 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 20 Apr 2009 14:58:35 -0400 Subject: NFS: Fix the XDR iovec calculation in nfs3_xdr_setaclargs Commit ae46141ff08f1965b17c531b571953c39ce8b9e2 (NFSv3: Fix posix ACL code) introduces a bug in the calculation of the XDR header iovec. In the case where we are inlining the acls, we need to adjust the length of the iovec req->rq_svec, in addition to adjusting the total buffer length.
