I'm fine to use sysfs that's not the point, if you've to add a ksmctl device, then sysfs is surely better. Besides ksm would normally be enabled at boot, tasks jailed by selinux will better not start/stop this thing. If people wants /sys/kernel/mm/ksm instead of the start_stop ioctl we surely can add it (provided there's a way to intercept write to the sysfs file). Problem is registering memory could also be done with 'echo 0 -1 >/proc/self/ksm' and be inherited by childs, it's not just start/stop. I mean this is more a matter of taste I'm afraid... Personally I'm more concerned about the registering of the ram API than the start/stop thing which I cannot care less about, so my logic is that as long as this pseudodevice exists, we should use it for everything. If we go away from it, then we should remove it as a whole. -- 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
