    There is no "buffer cache" in Linux. There is a pagecache for /etc/passwd
    and there is a pagecache for /dev/hda1. They are treated pretty much
    identically. The kernel attaches buffer_heads to those pagecache pages
    when needed - generally when it wants to deal with individual disk blocks.
