Revision f9ebd61855253078fe8b07bacaf516337f8078e8 authored by Anna Schumaker on 15 April 2015, 17:00:04 UTC, committed by Trond Myklebust on 23 April 2015, 19:16:13 UTC
The idmapper is completely internal to the NFS v4 module, so this macro will always evaluate to true. This patch also removes unnecessary includes of this file from the generic NFS client.
