Analysis
This bug has the same root cause of 'commit 7f27ec978b0e ("ocfs2: call
ocfs2_journal_access_di() before ocfs2_journal_dirty() in
ocfs2_write_end_nolock()")'. For this bug, jbd2_journal_restart() is
called by ocfs2_split_extent() during defragmenting.
How to fix
For ocfs2_split_extent() can handle journal operations totally by itself.
Caller doesn't need to call journal access/dirty pair, and caller only
needs to call journal start/stop pair. The fix method is to remove
journal access/dirty from __ocfs2_move_extent().
