But if you want to take the position that it's not the kernels job to keep the users head screwed on straight, I won't argue. Besides, when you wrote "I don't know how to sanely expose the damn things", I instinctively took that as a challenge to present a way. == I still like the position I thought you took for a moment there, of tightening, not loosening, the preconditions on setaffinity, starting with backing out the changes made to it this week. Are you still thinking of doing that, or would you rather just let this dog go back to sleep, as it lies now? -- I won't rest till it's the best ...
