fd1 = open(...);
ptr1 = mmap(fd1, ...);
close(fd1);

fd2 = open(...);
assert(fd1 == fd2);
ptr2 = mmap(fd2, ...);
close(fd2);

munmap(ptr1, ...);
munmap(ptr2, ...);

...what should appear in the logs here? How are you going to tell which
fd each munmap() belongs to?
Maybe you mean "log inode/device for the file" and not "original fd",
and then if/when you get confused it doesn't matter?
