    ocfs2: _really_ sync the right range · 64b4e252

    "ocfs2 syncs the wrong range" had been broken; prior to it the
    code was doing the wrong thing in case of O_APPEND, all right,
    but _after_ it we were syncing the wrong range in 100% cases.
    *ppos, aka iocb->ki_pos is incremented prior to that point,
    so we are always doing sync on the area _after_ the one we'd
    written to.
