I'm not sure what you're thinking here. Instead of my asking a dozen stupid questions, I guess I should just ask you to explain what you have in mind more. The function call you show above has no 'mask' argument, so I don't know what you intend to update mems_allowed to. Currently, a task mems_allowed is only updated in task context, from its cpusets mems_allowed. The task mems_allowed is updated automatically coming into the page allocation code, if the tasks mems_generation doesn't match its cpusets mems_generation. -- I won't rest till it's the best ...
