    Patch in this message
    Subject[31/50] Correctly close old nfsd/lockd sockets.
    From: Neil Brown <>

    commit 7a1fa065a0264f6b3d3003ba5635289f6583c478 in mainline.

    Commit aaf68cfbf2241d24d46583423f6bff5c47e088b3 added a bias
    to sk_inuse, so this test for an unused socket now fails. So no
    sockets get closed because they are old (they might get closed
    if the client closed them).

    This bug has existed since 2.6.21-rc1.

    Thanks to Wolfgang Walter for finding and reporting the bug.
