    So this does proportional write bandwidth division on bdi for buffered
    writes?

    > - support blkio.throttle.buffered_write_bps

    This is absolute limit systemwide or per bdi?

    Hi Fengguang,

    Only patch 0 and patch 4 have shown up in my mail box. Same seems to be
    the case for lkml. I am wondering what happened to rest of the patches.

    Will understand the patches better once I have the full set.

    Thanks
    Vivek
