From 7f51beddadbc7d879a4f0979c1cf330f7010161a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Thu, 26 Aug 2021 19:26:56 +0200 Subject: [PATCH] hw/virtio: Document virtio_queue_packed_empty_rcu is called within RCU MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit While virtio_queue_packed_empty_rcu() uses the '_rcu' suffix, it is not obvious it is called within rcu_read_lock(). All other functions from this file called with the RCU locked have a comment describing it. Document this one similarly for consistency.
