Can we confirm what is being proposed?  From following this thread, I
think what folks are suggesting is:

1)  Revert the current "ext3/4: wait on all pending ocmmits in ext3/4_sync_fs"

2)  Apply Jan's patch "jbd[2]: Fix return value of journal_start_commit()"

3)  Also apply Jan's patch "jbd2: Skip commit of a transaction without
any buffers" since it appears to be a good optimization (although it's
not clear it would happen once we revert (1), above.
