From: Darrick J. Wong <djwong@xxxxxxxxxx> The realtime section ends at the last rt extent. If the user configures the rt geometry with an extent size that is not an integer factor of the number of rt blocks, it's possible for there to be rt blocks past the end of the last rt extent. These tail blocks cannot ever be allocated and will cause corruption reports if the last extent coincides with the end of an rt bitmap block, so do not report consider them for the GETFSMAP output.
