函数名称:Check that the data written to an RCU-allocated object survives* reallocation.
函数原型:static int __init do_kmem_cache_rcu_persistent(int size, int *total_failures)
返回类型:int
参数:
| 类型 | 参数 | 名称 |
|---|---|---|
| int | size | |
| int * | total_failures |
| 276 | maxiter等于1024 |
| 277 | bool fail = false |
| 281 | buf等于kmem_cache_alloc(c, GFP_KERNEL) |
| 283 | fill_with_garbage(buf, size) |
| 284 | buf_contents等于kmalloc(size, GFP_KERNEL) |
| 285 | 如果非buf_contents则转到:out |
| 287 | used_objects等于分配数组内存 |
| 288 | 如果非used_objects则 |
| 289 | kfree(buf_contents) |
| 290 | 转到:out |
| 292 | 内存复制(buf_contents, buf, size) |
| 293 | kmem_cache_free(c, buf) |
| 299 | buf等于kmem_cache_alloc(c, GFP_KERNEL) |
| 300 | used_objects[iter]等于buf |
| 302 | fail等于memcmp(buf_contents, buf, size) |
| 303 | 以i小于等于iter循环kmem_cache_free(c, used_objects[i]) |
| 305 | 转到:free_out |
| 309 | free_out : |
| 310 | 删除高速缓存区 |
| 311 | kfree(buf_contents) |
| 312 | kfree(used_objects) |
| 313 | out : |
| 314 | total_failures加等于fail |
| 315 | 返回:1 |
