The patch looks valid to me, as the "index" member is not set in the
"btp == NULL" case, and so has a junk value in the caller, and it's
being used to index an array,
BUT - isn't it also necessary to set the "split_pages" member to 0,
because it also is not currently being set, and so too will have a
junk value in this case (and it's possible for it to be referenced by
the caller in this case).
The "btp == NULL" case is not hit by any existing test cases, and does
seem to be a rare case.
