    How does one mark it apropriately?
    The commit 51b1bd2 (oom: deprecate oom_adj tunable, see below)
    added it to feature-removal-schedule.txt, a patch for
    Documentation/ABI has also been provided in the meantime, if i'm not
    mistaken.

    And there is already a patch for openssh:
    https://bugzilla.mindrot.org/show_bug.cgi?id=1838

    commit 51b1bd2ace1595b72956224deda349efa880b693

    oom: deprecate oom_adj tunable

    /proc/pid/oom_adj is now deprecated so that that it may eventually be
    removed. The target date for removal is August 2012.

    A warning will be printed to the kernel log if a task attempts to use this
    interface. Future warning will be suppressed until the kernel is rebooted
    to prevent spamming the kernel log.
