We have namespaces, so use them for all vfs-exported namespaces so that filesystems can use them, but not anything else. Some in-kernel drivers that do direct filesystem accesses (because they serve up files) are also allowed access to these symbols to keep 'make allmodconfig' builds working properly, but it is not needed for Android kernel images.
