Hi Dave & Michael, In the V2, both of you thought that the memory I allocated for the bitmap i= s 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 abo= ut the changes, so I am not=20 sure whether that is OK or not, that's the why I resend the V3, I just want= your opinions about that part.=20 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?=20 Thanks! Liang -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
