From ff4e233d8ab70fe6ae460ecc8c0e5b24dd0fedb0 Mon Sep 17 00:00:00 2001 From: Nam Cao Date: Wed, 9 Jul 2025 21:21:15 +0200 Subject: rv: Let the reactors take care of buffers Each RV monitor has one static buffer to send to the reactors. If multiple errors are detected simultaneously, the one buffer could be overwritten. Instead, leave it to the reactors to handle buffering.
