[PATCH 1/2] ext4: MMP: kmmpd should use nodename from init_uts_ns.name, not sysname

[Nikitas Angelinas]

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.
