Did you look at the placement using pahole as to how this structure now
looks?

thanks for all your commnts. for this one, do you mean I need to remove the
blank line?  thanks

No, I mean to use the tool 'pahole' to see the structure layout that you
just created and determine if it really is the best way to add these new
fields, especially as you are adding huge buffers with odd alignment.
