All the on-disk data structures you define in this file have naturally
aligned members, so the __packed attribute is not needed.
However, I think it causes gcc to generate larger and slower code
on some architectures, because now it has to assume that the data
structure itself has no more than byte alignment.
I'd simply remove all instances of __packed therefore. In order
to verify that you got it right in all cases, build with
'-Wpadded -Wpacked'.
