Re: XFS Update for 2.6.19 - take 2

[Vlad Apostolov <vapo@sgi.com>]

I don't know what I have done wrong but some of the patches bellow signed
by me a actually patches from the comunity that I just have verified and
checked in our XFS source management system. I guess, I didn't clearly 
identified
the real authors of the fixes (although I think I put their names when I 
checked in
the patch).
