For the Fixes: tag: Fixes: 53069d4e76954e2e63c1b3c501051c6fbcf7298c ("Ocfs2/move_extents: move/defrag extents within a certain range.") This commit introduced __ocfs2_move_extents_range() with the while loop that calls ocfs2_get_clusters() (which caches extent data) followed by ocfs2_move_extent()/ocfs2_defrag_extent() (which modify disk), but without invalidating the extent cache afterwards. Thanks, Deepanshu
