This affinity may change later on.
I didn't use affinity that much but from manual it seems that if you own process you can set affinity as you like. IMHO this patch introduce a delay in io thread creation due to posting thread creation to another thread just to set different affinity.
It does. But aio threads have a long life, so this happens very rarely. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
