Subject: [PATCH 1/2] ext4: MMP: kmmpd should use nodename from init_uts_ns.name, not sysname
Date: Fri, 23 Sep 2011 01:23:08 +0100 [thread overview]
Message-ID: <1316737389-5522-2-git-send-email-nikitas_angelinas@xyratex.com> (raw)
In-Reply-To: <1316737389-5522-1-git-send-email-nikitas_angelinas@xyratex.com>
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.
