Yes my bad, it should be added in the end.
But abi script will still shout for 'void*[4]' to 'void*[3]' conversion.
We may need to add something in the devtools/libabigail.abignore
So that, CI is not broken when reserved fields are changed.
Otherwise, it does not make sense to introduce reserve fields.
Can we have something generic for reserved fields?
Any suggestions?
