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

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
