for ArrayBuffer whose buffers are not own by BackingStore. This
would help us avoid problem with the new V8 BackingStore API where new
ArrayBuffer is allocated at the same place of previous ArrayBuffer
that is still being tracked in BackingStore table.

Ref: #31052

LGTM, but could you revert the variable name change in src/node_buffer.cc. The diff isn't big, but the name change is distracting.

This does not land cleanly on v13.x. Please open a manual backport in case this should be backported or leave a comment to update the labels in case it should not be backported.

/cc @addaleax should this PR be backported to v13.x?

@thangktran I think it might be good to backport it, and the conflicts are likely going to be easy to resolve, but it’s definitely not critical.

I'll prepare a PR for this.

@addaleax i realized that this PR depends partially on some changes from #30782 which is not in v13.x-staging yet.

https://github.com/thangktran/node/blob/850a80b8a7b2fc8e1fcc3956c2860c3042576975/src/node_http2.h#L992

should i cherry-pick both to the backport PR?

@thangktran We marked that one as semver-major, so I don’t think we can do that really … I’ll just mark this PR here as dont-land-on-v13.x and we should be fine :)
