From 7a048cec598e1761cdcd63eb3a3c6e390b7661c7 Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Tue, 9 Oct 2018 18:09:59 +0200 Subject: xen: drop writing error messages to xenstore xenbus_va_dev_error() will try to write error messages to Xenstore under the error//error node (with something like "device/vbd/51872"). This will fail normally and another message about this failure is added to dmesg. I believe this is a remnant from very ancient times, as it was added in the first pvops rush of commits in 2007. So remove the additional message when writing to Xenstore failed as a minimum step.
