Yeah, I know. The problem is that each patch must compile and run. They can't be split up without violating that unfortunately. > Why manually copy these fields after a kmemdup? Fair point. Fixed. > What about the task backpointer? (i.e. tsec2->task) The problem is that there can't be one with this patch as the task_security struct and the LSM security data attached to it may outlive the task it points back to. It seems that the backpointer can be dispensed with. Nothing particularly seems to use it. Do you know the reason for its existence?
