Hi all, I've rebased the series to rewrite the delalloc handling to handle the race where another thread moves extents from the COW to the data fork on top of the ' xfs: properly invalidate cached writeback mapping' series from Brian. The first patch is a FOLD for that series as those changes should go into the original patches. To make reviewing easier I also have a git tree available here: git://git.infradead.org/users/hch/xfs.git xfs-mapping-validation.3 Gitweb: http://git.infradead.org/users/hch/xfs.git/shortlog/refs/heads/xfs-mapping-validation.3
