如何处理remove_proc_entry失败的情况？

netentsec

如果remove_proc_entry执行中报错，应用计数非0，deleted标志为1，那么返回之后该如何处理？
一直循环到de->count为0？但是de结构本身有可能随时被释放？

void remove_proc_entry(const char *name, struct proc_dir_entry *parent)
{
.........
                if (!atomic_read(&de->count))
                        free_proc_entry(de);
                else {
                        de->deleted = 1;
                        printk("remove_proc_entry: %s/%s busy, count=%d\n",
                                parent->name, de->name, atomic_read(&de->count));
                }
...........
}

此外，From LDD 3rd，Chapter 4，Page 86

The most important problem is with removal of /proc entries. Such removal may well
happen while the file is in use, 【as there is no owner associated to /proc entries, so
using them doesn’t act on the module’s reference count.】 This problem is simply triggered
by running sleep 100 < /proc/myfile just before removing the module, for example.

【】里面的话怎么理解？为什么说no owner？
