[ Upstream commit2d408c0d45] Commitf599c64fdf("xen-netfront: Fix race between device setup and open") changed the initialization order: xennet_create_queues() now happens before we do register_netdev() so using netdev->name in xennet_init_queue() is incorrect, we end up with the following in /proc/interrupts: 60: 139 0 xen-dyn -event eth%d-q0-tx 61: 265 0 xen-dyn -event eth%d-q0-rx 62: 234 0 xen-dyn -event eth%d-q1-tx 63: 1 0 xen-dyn -event eth%d-q1-rx and this looks ugly. Actually, using early netdev name (even when it's already set) is also not ideal: nowadays we tend to rename eth devices and queue name may end up not corresponding to the netdev name. Use nodename from xenbus device for queue naming: this can't change in VM's lifetime. Now /proc/interrupts looks like 62: 202 0 xen-dyn -event device/vif/0-q0-tx 63: 317 0 xen-dyn -event device/vif/0-q0-rx 64: 262 0 xen-dyn -event device/vif/0-q1-tx 65: 17 0 xen-dyn -event device/vif/0-q1-rx Fixes:f599c64fdf("xen-netfront: Fix race between device setup and open") Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Reviewed-by: Ross Lagerwall <ross.lagerwall@citrix.com> Signed-off-by: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
