    Revert "writeback: do not sync data dirtied after sync start" · 0dc83bd3

    This reverts commit c4a391b5. Dave
    Chinner <david@fromorbit.com> has reported the commit may cause some
    inodes to be left out from sync(2). This is because we can call
    redirty_tail() for some inode (which sets i_dirtied_when to current time)
    after sync(2) has started or similarly requeue_inode() can set
    i_dirtied_when to current time if writeback had to skip some pages. The
    real problem is in the functions clobbering i_dirtied_when but fixing
    that isn't trivial so revert is a safer choice for now.
