Sure, if you are fine with that model, I'm fine with it too. You are
the one sending patches to mangle basic driver-core definitions to
paper-over some issues dm seem to have with it. I just object to such
core changes, not to the way dm is doing things.

I have no problem with dm creating "dead" devices, it's like this
since a long time, but please don't try to fake things in the driver
core to make it look different from what it is. We don't want /sys and
/dev and events to be out of sync, like non-"add"-ed devices which are
fully created in /sys, or "remove"-d devices which are still fully
populated in /sys.

/sys is the direct export of kernel objects, if you create objects,
they appear, and they get announced. If you don't want them to be
announced at that time, just don't register them at that time.

Don't get me wrong, I'm not asking you to change the current state how
dm is doing things, I just object to the patch which inconsistently
tries to fake events, which do not match the state in /sys.

Thanks,
Kay
