Not as such, no. There's been various CFS-like schemes floated for a squid fs
(Adrian, you were a proponent for one of them for a while, I seem to recall?).
Opinions are divided as to whether they'd work well or not - on the one hand,
CFS seems to work well for inn, which on the surface has a similar access
pattern (lots of small files being read semi-randomly and written almost
continuously), on the other, the expiry policies are likely to be somewhat
different (time-based, but we time out different types of files at different
times, which may mean CFS devolves to random writes if the disk is allowed to
fill up, or it may impose strict restrictions on how you expire files, or it
may mean lots of "re-shuffling" of files as you move around the disk -
depending on how it's all implemented).

If you hunt through the mailing list archives, I'm sure you'll find discussion
on these points in there from a year or two ago...
