[lug] XFS filesystem core code goes into AC series

[Nate Duehr]

Make sure to check out the different journaling modes on ext3 also.  I have
seen reports on the web that using the Data: Journaled mode vs. Data:
Ordered mode can increase performance (at only a slight loss of meta-data
information) dramatically.

There were a couple of good articles on IBM's DeveloperWorks site about ext3
a while back.  Good primer info.

I haven't had a chance to test the speed claims yet.  (And no, I won't take
their word for it.  GRIN...)

And it can not be done on the root partition, so if you're a fan of "make
the whole drive /" (I'm not, definitely.), you're out of luck.
