函数名称：test_mem_optimisations

函数原型：static void noinline __init test_mem_optimisations(void)

返回类型：void

参数：无

444  DECLARE_BITMAP(bmap1, 1024)
445  DECLARE_BITMAP(bmap2, 1024)
448  以start小于1024循环
449  以nbits小于1024减start循环
450  memset(bmap1, 0x5a, bmap1的长度)
451  memset(bmap2, 0x5a, bmap2的长度)
453  bitmap_set(bmap1, start, nbits)
454  __bitmap_set(bmap2, start, nbits)
455  如果非bitmap_equal(bmap1, bmap2, 1024)则
456  printk("set not equal %d %d\n", start, nbits)
457  failed_tests自加
459  如果非DOC: bitmap introduction* bitmaps provide an array of bits, implemented using an an* array of unsigned longs则
460  printk("set not __equal %d %d\n", start, nbits)
461  failed_tests自加
464  bitmap_clear(bmap1, start, nbits)
465  __bitmap_clear(bmap2, start, nbits)
466  如果非bitmap_equal(bmap1, bmap2, 1024)则
467  printk("clear not equal %d %d\n", start, nbits)
468  failed_tests自加
470  如果非DOC: bitmap introduction* bitmaps provide an array of bits, implemented using an an* array of unsigned longs则
471  printk("clear not __equal %d %d\n", start, nbits)
