The following error was encoutered in [1]:
FAILED elf_update(WRITE): no error
elf_update() returns the total size of the file which here happens to be
a ~2.5GB vmlinux file: this size overflows the integer used to hold the
return value of elf_update() and is then interpreted as being negative.
So fix this by using the correct type expected by elf_update() which is
off_t.
