Thanks for the self-correction, and I have another comment. In [v2 2/3], a pfn range check is removed as below: int -set_bitmap_cyclic(char *bitmap, unsigned long long pfn, int val) +set_bitmap_cyclic(char *bitmap, unsigned long long pfn, int val, struct cycle *cycle) { int byte, bit; - if (pfn < info->cyclic_start_pfn || info->cyclic_end_pfn <= pfn) - return FALSE; - However, "pfn" can be out of the range of cycles in the case of filtering free pages with free_list, because we have to look up whole free_list every cycle since free_list isn't sorted. So this range check should be moved to reset_bitmap_of_free_pages().
