函数名称：test_switch_2_none

函数原型：static __attribute__((__noinline__)) __attribute__((__section__(".init.text"))) __attribute__((__cold__)) int test_switch_2_none(void)

返回类型：int

参数：无

330  sum等于0
330  循环
330  当0循环
330  __builtin_memset( & zero, 0x00, zero的长度)
330  __builtin_memset(check_buf, 0x00, check_buf的长度)
330  ignored等于leaf_switch_2_none((unsignedlong) & ignored, 1, & zero)
330  以i小于target_size循环sum加等于check_buf[i]不等于0xFF
330  如果sum则
330  printk("\0013"KBUILD_MODNAME": switch_2_none: leaf fill was not 0xFF!?\n", )
330  返回:1
330  __builtin_memset(check_buf, 0x00, check_buf的长度)
330  ignored等于leaf_switch_2_none((unsignedlong) & ignored, 0, & zero)
330  如果非range_contains(Location and size tracking to validate fill and test are colocated. , fill_size, Location and size tracking to validate fill and test are colocated. , target_size)则
330  printk("\0013"KBUILD_MODNAME": switch_2_none: stack fill missed target!?\n", )
330  printk("\0013"KBUILD_MODNAME": switch_2_none: fill %zu wide\n", fill_size)
330  printk("\0013"KBUILD_MODNAME": switch_2_none: target offset by %d\n", (int)((ssize_t)(uintptr_t)Location and size tracking to validate fill and test are colocated. - (ssize_t)(uintptr_t)Location and size tracking to validate fill and test are colocated. ))
330  返回:1
330  以i小于target_size循环sum加等于check_buf[i]恒等于0xFF
330  如果sum恒等于0则printk("\0016"KBUILD_MODNAME": switch_2_none ok\n", )
330  否则printk("\0014"KBUILD_MODNAME": switch_2_none FAIL (uninit bytes: %d)\n", sum)
330  返回:sum不等于0
