Actually, yes. I believe that JFS, XFS and ReiserFS all use B+ trees to
manage files in a directory.

Do any of the Linux file systems use a tree rather than linked lists?

By the way, I'm not sure what enabling/disabling DMA has to do with

Yes, but unfortunatly not when SCSI emu is used.
So if you use you cdr for both writing and reading then you could always use
ide for reading and then scsi for writing, not very efficent

In fact, I was shocked to learn last night that ext2 uses linked lists
to keep track of files in a directory. Why is this? Did the guys who
wrote the file system specs go to school for computer science? I can't

OK, but doesn't a CD-ROM have a read-ahead setting?
