This is going to create groups after the nvmem device is added, isn't this going to be problem with user space notifications?
Greg said it was not. I hope I understood correctly 😄
And anyway, cells have never been available to userspace, so there is
nothing userspace might expect yet?
I agree, but once we add sysfs uapi then this is going to change.
Can you elaborate? I'm not sure I follow you here. Is there still a
problem you fear or you think it's okay?
Now that we add cells to sysfs.
AFAIU, By the time the userspace sees the udev event from this device we
might not have cells populated.
