Hi Kazu,

my patch doesn't really work :( The offset from 'init_uts_ns' to 'name'
has changed from 4 to 0 but how do you handle that in makedumpfile w/o
first knowing what kernel version that is. It is a chicken-and-egg
problem. Not sure how to solve it. The Linux kernel doesn't provide
the symbol 'init_ns_ns.name' as i initially thought and ,therefore,
i based my patch on a wrong assumption. It would be nice if kernel just
provided a symbol for 'init_uts_ns.name' instead of 'init_uts_ns' which
might change anytime.

Regards
Alex
