Customers do filtering from initramfs context. It is not practical to
save TB of memory and filter it later. And we just concluded that is
it not practical to do scrubbing from initramfs due to need of vmlinux.

So doing filtering and doing scrubbing will not happen at the same
time practically. So bloating size of makedumpfile does not make
sense to me.

Thanks
