[PATCH] NFS: Hide NFS server-generated readdir cookies from userland
NFSv3 currently returns the unsigned 64-bit cookie directly to
userspace. The following patch causes the kernel to generate
loff_t offsets for the benefit of userland.
The current server-generated READDIR cookie is cached in the
nfs_open_context instead of in filp->f_pos, so we still end up work
correctly under directory insertions/deletion.
