That was something I was wondering about also, and meant to do a search.
Hmm, a google search doesn't immediately show *why* it's the default in
Fedora, and I haven't been following LKML for the last three months so I
don't know how it's been fairing against the deadline and AS schedulers
lately.
It was merged into 2.6.6, but it looks like fc2 has been using it longer
than that.
