SubjectRe: Buffer and Page cache coherent? was: Strange IDE performance change in 2.6.1-rc1 (again)

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.
