now i use a initrd to boot my system, then switch to the real root
filesystem, and i want to reuse the initrd.
i see in the redhat, it use the blockdev --flushbufs /dev/ram0 to
flush the initrd ram.
and i can't find blockdev in busybox, so i use the freeramdisk
/dev/ram0, but it seems has no effect.is there any other command to
finish this job?

thanks for any hints

Best regards
