For this bug, jbd2_journal_restart() is\ncalled by ocfs2_split_extent() during defragmenting.\n\nHow to fix\n\nFor ocfs2_split_extent() can handle journal operations totally by itself. \nCaller doesn't need to call journal access/dirty pair, and caller only\nneeds to call journal start/stop pair. The fix method is to remove\njournal access/dirty from __ocfs2_move_extent().\n\nThe discussion for this patch:\nhttps://oss.oracle.com/pipermail/ocfs2-devel/2023-February/000647.html"
