Subject: Print IP address of unresponsive server
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=275516cdcfa42c603c79ea42d2a7d4288d950fea;p=deliverable%2Flinux.git

Print IP address of unresponsive server

Before this patch, only the hostname of the server
is printed when it becomes unresponsive.
This might not be helpful, if the IP-Address has
changed since initial mount when the name was
resolved (e.g. because the IPv6-Prefix changed).

This patch adds the cached IP address of the unresponsive server,
to the log message.
