XFS as Root Filesystem

[Tan Pong Heng <pongheng@xxxxxxxxxxxxxx>]

Hi, I have completed another round of testing with XFS as my root 
filesystem.
Attached is the dmesg output of my current system. I have also successfully
recompiled the kernel with make mrproper; cp .config; make oldconfig; 
make dep;
make bzImage modules.
It seems that XFS is very usable on linux now. I did notice a slight 
performance
degragation on this setup though....
