From b0fe545b3c64b327b1ef56ee57def6e1afa470a8 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Thu, 4 Dec 2025 12:25:17 -0500 Subject: [PATCH] tools/virtio: stub might_sleep and synchronize_rcu Add might_sleep() and synchronize_rcu() stubs needed by virtio_config.h. might_sleep() is a no-op, synchronize_rcu doesn't work but we don't need it to. Created using Cursor CLI. Message-ID: <5557e026335d808acd7b890693ee1382e73dd33a.1764873799.git.mst@redhat.com> Acked-by: Jason Wang Signed-off-by: Michael S.
