Hi @lialan , I'd appreciate a bit more high-level explanation.

> This patch expands the store into two (maybe atomic) rmw partial stores (for the first and the third byte), and a non-atomic single full byte store (for the second byte).

Could you define what "atomic" and "non-atomic" means in the context of this patch? Also, it's not clear to me what "new" is being introduced? Pseudo-code with "what we have today" vs "what this PR enables" would be appreciated.
