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;
