Andi Kleen 2724b6db66 [PATCH] x86-64: Shut up warnings for vfat compat ioctls on other file systems 
vfat implements compat handlers for these ioctls, but when they
were executed on other file systems the kernel would still complain
about an unknown compat ioctl.  Just declare them as compatible
and let them be rejected when not needed by the normal path.

This makes wine runs a lot quieter
