SAFE_MMAP()


Moreover the whole intialization up to this point should be done in
setup().

This can be easily converted to an array of structures describing the
test and exported as separate tests in the struct tst_test

The munmap() should rather be done in cleanup but only if the file has
been mmaped().

The fd can be closed right after the mmap().
