PS2, Line 9: It's not valid to separately check the major and minor versions. The
           : proper minor check would be something like:
           : 
           :   if (fmap->ver_major == FMAP_VER_MAJOR &&
           :       fmap->ver_minor > FMAP_VER_MINOR)
Brian, thank you so much for lots of details and links, this is really cool!
I thought more about it, and I think the patch is fine, please don't drop it :)

However, I found one gem in cbfstool code , which is a comment for the `is_valid_fmap` function,

/* Make a best-effort assessment if the given fmap is real */

If you could add this comment to the functions, that would be it! Thank you!

This is so nice of you, I appreciate a lot!
