__pfn_to_section is defined as __nr_to_section(pfn_to_section_nr(pfn)). Since we already get section_nr, it is not necessary to get mem_section from start_pfn. By doing so, we reduce one redundant operation. Link: http://lkml.kernel.org/r/20190809010242.29797-1-richardw.yang@linux.intel.comSigned-off-by:
