From 3a63e2d29bb2fd92577d42aeb8fa956ae18df22e Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Fri, 2 Oct 2020 10:17:41 -0400 Subject: [PATCH 02/14] qga/commands-posix: Move the udev code from the pci to the generic function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RH-Author: Thomas Huth Message-id: <20201002101742.249169-3-thuth@redhat.com> Patchwork-id: 98526 O-Subject: [RHEL-8.4.0 qemu-kvm PATCH 2/3] qga/commands-posix: Move the udev code from the pci to the generic function Bugzilla: 1755075 RH-Acked-by: Danilo de Paula RH-Acked-by: Cornelia Huck RH-Acked-by: David Hildenbrand The libudev-related code is independent from the other pci-related code and can be re-used for non-pci devices (like ccw devices on s390x). Thus move this part to the generic function. Buglink: https://bugzilla.redhat.com/show_bug.cgi?id=1755075 Signed-off-by: Thomas Huth Reviewed-by: Daniel P.
