Subject: [PATCH AUTOSEL 5.4 068/459] nfs: NFS_SWAP should depend on SWAP

From: Geert Uytterhoeven <>

[ Upstream commit 474c4f306eefbb21b67ebd1de802d005c7d7ecdc ]

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.

Fixes: a564b8f0398636ba ("nfs: enable swap on NFS")
