commit c0b00a5 ("dma-buf: update debugfs output") modified the
default exporter name to be the KBUILD_MODNAME pre-processor
macro instead of __FILE__ but the documentation was not updated.
Also the "Supporting existing mmap interfaces in exporters" section
title seems wrong since talks about the interface used by importers.

Similar to the motivation for kernel cpu access it is again important that
