函数名称：No initialization without compiler instrumentation.

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

返回类型：int

参数：无

276  sum等于0
276  循环
276  当0循环
276  __builtin_memset( & zero, 0x00, zero的长度)
276  __builtin_memset(check_buf, 0x00, check_buf的长度)
276  ignored等于No initialization without compiler instrumentation.
276  以i小于target_size循环sum加等于check_buf[i]不等于0xFF
276  如果sum则
276  printk("\0013"KBUILD_MODNAME": user: leaf fill was not 0xFF!?\n", )
276  返回:1
276  __builtin_memset(check_buf, 0x00, check_buf的长度)
276  ignored等于No initialization without compiler instrumentation.
276  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
276  printk("\0013"KBUILD_MODNAME": user: stack fill missed target!?\n", )
276  printk("\0013"KBUILD_MODNAME": user: fill %zu wide\n", fill_size)
276  printk("\0013"KBUILD_MODNAME": user: 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. ))
276  返回:1
276  以i小于target_size循环sum加等于check_buf[i]恒等于0xFF
276  如果sum恒等于0则printk("\0016"KBUILD_MODNAME": user ok\n", )
276  否则printk("\0014"KBUILD_MODNAME": user FAIL (uninit bytes: %d)\n", sum)
276  返回:sum不等于0
