I don't know. The message containing the patches doesn't seem to have made it
into either the LKML or the linux-fsdevel mailing lists.

The basic code can be found in:

http://cvs.infradead.org/cgi-bin/cvsweb.cgi/afs/

In directories:

Documentations/filesystems/
include/linux/
fs/cachefs/

I'll see about putting the patch up for download when I get to OLS.

Random question:

Way back when I used union mount code (under OS/2) that would mount the first
filesystem read-only, and allow you to cache changes to it in a second
filesystem. (So you could do a build of slightly self-modifying code, a lot
like the Linux build in 2.4 was, against a read-only tree.)

Would this be a good tool for that sort of application? (There's all sorts of
other "trial run" type applications; running stuff against database snapshots
and then seeing what the deltas are, etc...)
