[openib-general] device add/remove in userspace

[Sean Hefty]

Is there a way for a userspace application to know if a device has been added or 
removed?

I'm porting the CMA to userspace.  One of the features of the kernel CMA is that 
listen requests can span all devices, with device add/remove handled 
automatically.  I'd like to expose similar functionality in userspace, but it 
appears that the device list is built once when ibv_get_devices() is called.
