Might not be worth applying as-is as the per-page callback is very ineffcient. What XFS really wants is a callback when writeout of a whole extent has completed. This delayed i_size updates scheme might be worthwile for btrfs aswell, btw. Signed-off-by: Christoph Hellwig Signed-off-by: Chris Mason --- Reading git-diff-tree failed
