Re: [v6 09/15] sparc64: optimized struct page zeroing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add an optimized mm_zero_struct_page(), so struct page's are zeroed without
calling memset(). We do eight to tent regular stores based on the size of
struct page. Compiler optimizes out the conditions of switch() statement.

Again, this doesn't explain why we need this. You have mentioned those
reasons in some previous emails but be explicit here please.


I will add performance data to this patch as well.

Thank you,
Pasha
