Hi Dave & Michael,
In the V2, both of you thought that the memory I allocated for the bitmap is too large, and gave some
suggestions about the solution, so I changed the implementation and used scattered pages for the bitmap
instead of a large physical continued memory. I didn't get the comments about the changes, so I am not
sure whether that is OK or not, that's the why I resend the V3, I just want your opinions about that part.
I will implement the new schema as Dave suggested in V4. Before that, could you take a look at this version and
give some comments?
Thanks!
Liang
