From 6ea0a4679d6a11c66cfeb26d15244fb6f9b52d14 Mon Sep 17 00:00:00 2001 From: Anthony Liguori Date: Mon, 7 Apr 2008 15:33:16 -0500 Subject: [PATCH] virtio_net: remove overzealous printk The 'disable_cb' is really just a hint and as such, it's possible for more work to get queued up while callbacks are disabled. Under stress with an SMP guest, this printk triggers very frequently. There is no race here, this is how things are designed to work so let's just remove the printk.
