+am-utils-6.2 - fix nfsv3 fh length in NFS_FH_DREF()
+
+From: Ian Kent <ikent@redhat.com>
+
+The NFS_FH_DREF() macro for linux uses sizeof(struct nfs_fh) for the
+length of the file handle copy regardless of the version of NFS used.
+
+But NFSv3 file handles are 64 bytes and not copying the whole file
+handle can cause automounts to fail.
+
+Changing this to use the size of the passed nfs file handle fixes
+the problem.
+
+Signed-off-by: Ian Kent <ikent@redhat.com>
