Hi all, this series contains my changes to fix up the delalloc and reflink code to prepare for the always COW mode. This sits on top of the 'xfs: properly invalidate cached writeback mapping' series from Brian. To make reviewing easier I also have a git tree available here: git://git.infradead.org/users/hch/xfs.git xfs-mapping-validation.5 Gitweb: http://git.infradead.org/users/hch/xfs.git/shortlog/refs/heads/xfs-mapping-validation.5 Changes since v1: - fix the ilock hold time in delalloc conversions (Darrick) - switch handling of a 0 block allocation from an assert to a runtime error - fix an off by one false negative in an assert - move extent trimming from xfs_convert_blocks to the caller - update a few commit logs
