fs/nfs/super.c:

case Opt_sharecache:
mnt->flags &= ~NFS_MOUNT_UNSHARED;
break;
case Opt_nosharecache:
mnt->flags |= NFS_MOUNT_UNSHARED;
mnt->options &= ~NFS_OPTION_FSCACHE;
break;
case Opt_fscache:
/* sharing is mandatory with fscache */
mnt->options |= NFS_OPTION_FSCACHE;
mnt->flags &= ~NFS_MOUNT_UNSHARED;
break;
case Opt_nofscache:
mnt->options &= ~NFS_OPTION_FSCACHE;
break;
Hmmm... Actually, I'm not sure this is sufficient.
