From daa782262efe0de83e61e7b0d2862fc377f5226d Mon Sep 17 00:00:00 2001 From: Michael Kelley Date: Sat, 17 Oct 2026 09:08:48 -0700 Subject: [PATCH] Documentation: hyperv: Update information on guest CPU offlining In Hyper-V Overview documentation, remove the out-of-date reference to explicitly reassigning VMBus channel interrupts before taking a guest CPU offline. Instead, reference the VMBus documentation, which is already up-to-date on this topic.
