[dm-devel] [RFC] Message ioctl direct to device

[christophe varoqui]

> That ioctl interface is just plain horrible, it should really stay out 
> of view inside libdevmapper in case somebody notices.  And we do not 
> want to make libdevmapper a dependency just to ioctl the virtual 
> device.  Going through libdevmapper makes plenty of sense for things 
> like suspend/resume where there is a lot of deadlock-prevention logic 
> that has to be followed rigorously, but no sense whatsoever for what I 
> use this interface, and what I expect other people might use it for.  
> Of course, you are one of those "other people", I think, with 
> multipath, so it would help if you tell me what you have in mind there.
