Hello All,

I'm running DSS (Darwin Streaming Server) on one of my servers and that
"Concurrent Multi-File Data Streams" thing seems very interesting :)

I have a separate partition there I store all movies.
Is 2.6.22 kernel already has this patch incorporated already(actually
gentoo-sources-2.6.22-r5)?

Are there any special mkfs.xfs or mount options I should make to make this
thing work or make the FS to be optimized for streaming?
