Move "exit_robust_list" into mm_release() and clear them We don't want to get rid of the futexes just at exit() time, we want to drop them when doing an execve() too, since that gets rid of the previous VM image too. Doing it at mm_release() time means that we automatically always do it when we disassociate a VM map from the task.

In the future, could you reference which kernel contained these patches so I don't have to go look it up? :) For the record, the first one showed up in 2.6.28-rc5 and the second in 2.6.32-rc4. thanks, greg k-h
