Solved: Can't mount XFS root if HFS enabled

[Nick Wellnhofer <wellnhofer@xxxxxxxx>]

This might be helpful to XFS users:

With Linux 2.6.4 and later versions I couldn't boot from my XFS root 
partition. I eventually found out that the new HFS driver which I had 
enabled was the culprit. The kernel first tried to mount the root fs as 
HFS and due to a wrong return value it bailed out.

If you have HFS enabled and want to boot from a XFS root partition you 
should pass "rootfstype=xfs" as boot parameter or apply the attached 
patch (against fs/hfs/super.c in 2.6.5).

This also might explain the problem John Palkovic posted here:

I have forwarded the fix to the HFS maintainer and hope to see it in a 
release kernel soon.

Nick
