From: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx> Christoph sent me a patch a few months ago called "XFS THP wip". I've redone it based on current linus tree, plus the page_size() / compound_nr() / page_shift() patches currently found in -mm. I fixed the logic bugs that I noticed in his patch and may have introduced some of my own. I have only compile tested this code.
