SubjectPurging the Buffer Cache
  Is there any way to completely purge the buffer
cache -- not just the write requests (ala 'sync' or
'update'), but the whole thing? Can I just call
invalidate_buffers() or destroy_buffers()?

I know, why in the world would a person do such a
thing? Research. It'd be easier for me to write a
little program or add it to a module than wait for a
reboot each time I need a clean buffer cache.

Thanks in advance,
