    [PATCH] xip: reduce code duplication · eb6fe0c3

    This patch reworks filemap_xip.c with the goal to reduce code duplication
    from mm/filemap.c.  It applies agains 2.6.12-rc6-mm1.  Instead of
    implementing the aio functions, this one implements the synchronous
    read/write functions only.  For readv and writev, the generic fallback is
    used.  For aio, we rely on the application doing the fallback.  Since our
    "synchronous" function does memcpy immediately anyway, there is no
    performance difference between using the fallbacks or implementing each
