    Subject[PATCH 3.16 52/99] nfs: NFS_SWAP should depend on SWAP
    3.16.84-rc1 review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Geert Uytterhoeven <geert+renesas@glider.be>

    commit 474c4f306eefbb21b67ebd1de802d005c7d7ecdc upstream.

    If CONFIG_SWAP=n, it does not make much sense to offer the user the
    option to enable support for swapping over NFS, as that will still fail
    at run time:

    # swapon /swap
    swapon: /swap: swapon failed: Function not implemented

    Fix this by adding a dependency on CONFIG_SWAP.

    This option enables swapon to work on files located on NFS mounts.
