remove all the code which was trying to do so. This code was nasty in several ways, it was hiding the kernel bug where the kernel was unable to properly load a module, and it was quitting if it wasn't able to load the module. The consequence is that an ABI breakage of the vfsconf API would have broken *every* mount utility.
