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 Regards, Flo commit 51b1bd2ace1595b72956224deda349efa880b693 Author: David Rientjes Date: Mon Aug 9 17:19:47 2010 -0700 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.
