Abhishek Gupta, did you really quote the right mails? Because those mails are just proving my point, it makes no sense to have an unconditional userspace rule which is just there to always enable new memory. To the contrary, as this is always going to involve more memory allocation (like it might spawn a new udev worker), it's much more prone to fail in userspace than in kernel space. This would make more sense if, as the thread suggests, you want to pre-add memory without activating it yet (I have no idea why this would be useful, but I don't claim to have a full understanding of all the use cases here), but then we shouldn't have that udev rule.
