From 215fc6af739d2dfdcad5496248d0d6302eb8a604 Mon Sep 17 00:00:00 2001 From: Nikitas Angelinas Date: Tue, 18 Oct 2011 10:49:51 -0400 Subject: [PATCH] ext4: MMP: kmmpd should use nodename from init_uts_ns.name, not sysname sysname holds "Linux" by default, i.e. what appears when doing a "uname -s"; nodename should be used to print the machine's hostname, i.e. what is returned when doing a "uname -n" or "hostname", and what gethostname(2)/sethostname(2) manipulate, in order to notify the administrator of the node which is contending to mount the filesystem.
