I'm a newbie in kernel hacking and I'm confused with the buffer/page cache.
As far I have understood the buffer cache is for buffering block devices
data and the page cache for buffering filesystems' file data. But when the
command "cat /dev/hda > /dev/null" runs, the "free" command reports that
'cached' is growing and 'buffers' are shrinking. Can anyone figure out what
have I misunderstood?
