Hi tachibana-san,

I have makedumpfile filtering working now.  Much thanks.

Examples of filtering on a 1 GB x86_64 system, booted with
"crashkernel=64M at 16M" and then crashed (sysrq-c).

Various makedumpfile -d values and their results:

makedumpfile -d 1 -E -i vmcore.info vmcore.002 dump002.omit.zero 
makedumpfile -d 17 -E -i vmcore.info vmcore.002 dump002.omit.zero.free
makedumpfile -d 23 -E -i vmcore.info vmcore.002 dump002.omit.zero.free.all.cache
makedumpfile -d 31 -E -i vmcore.info vmcore.002 dump002.omit.all
