So it looks like you do two things.
- make it a real pointer (which it should be), when it's
  used to keep track of the transaction a buffer is
  associated with; and
- eliminate the use of this field storing cast 1's and 2's
  for verifying the way log buffers are used.

I don't see much value in the second one, and the first
is the way it should be, so this looks good to me.
