Well ... actually I'd have to agree with that. I chose a filesys interface for cpusets for similar reasons. However in this case, the added functionality seems so close to mbind/mempolicy that one has to at least give consideration to remaining consistent with that style of interface. These questions of interface style (filesys or syscall) probably don't matter, however. at least not yet. First we need to make sense of the larger issues that Ken and Andi raise, of whether this is a good thing to do. -- I won't rest till it's the best ...
