A slew of changes to allow vmware3 to work on 5.x with dynamic device
numbering while not breaking 4.x compatibility:
- Stop using device nodes in /usr/compat/linux/dev and instead rely
on the linuxaltor passing though to /dev
- Create needed device nodes in /dev (on 4.x)
- Account for a change in falloc's semantics that was preventing
the vmmon module from being unloaded on 5.1+ machines.
