Commit b46e756f ("thp: extract khugepaged from mm/huge_memory.c") moved code from huge_memory.c to khugepaged.c. Some of this code should be compiled only when CONFIG_SYSFS is enabled but the condition around this code was not moved into khugepaged.c. The result is a compilation error when CONFIG_SYSFS is disabled: mm/built-in.o: In function `khugepaged_defrag_store': khugepaged.c:(.text+0x2d095): undefined reference to `single_hugepage_flag_store' mm/built-in.o: In function `khugepaged_defrag_show': khugepaged.c:(.text+0x2d0ab): undefined reference to `single_hugepage_flag_show' This commit adds the #ifdef CONFIG_SYSFS around the code related to sysfs.
