Patch 4 and 6 are really part of the implementation of 2 different functions (locking memory and guaranteeing single virtual address). Yes, they both add a flag, but isn't strange to do 2 different unrelated things in one patch? If you insist, I can merge, but it feels wrong to me... When it comes to the other remark, I can leave the other lines untouched, but the code is easier to read when comments are aligned (in the final file, not in the patch, I agree). How do one normally do that (like touching old lines to make thing more pretty when the new lines comes)? Just another patch adding space and reformating comments?. Or we don't care about comment/code alignment? Thx :-) Christophe.
