I am not talking about the kernel buffers.
I am referring to the buffer cache on the disks. There will be a need to
flush/force write completion of data to the disk before power down if I
enable the intelligent write-caching in the hardware.
Do if something exists, what do I need look for or hook to issue flush
cache during a halt/reboot event?
