这个字符串会被传递给printk，然后它会被一个管理缓冲边界(emit_log_char)的特殊函数复制到内核日志缓冲区中。

通过使用一个软引用来管理高速缓存的缓冲区，可以解决LeakyChecksum中的问题，如清单2所示。
We can fix the problems in LeakyChecksum by using a soft reference to manage the cached buffer, as shown in Listing 2.
缓冲区的获取是通过使用锁存器（latch）和锁访问信息来管理的，该锁存器称作 mutex。
Buffer acquisition is managed through the use of latches, known as mutex, and lock-access information.
所有的缓冲区将被组织到一个较长的最近最少使用(least - recently - used,LRU)缓冲区队列中，并通过最近最少使用(LRU)机制进行管理。
All buffers are organized into a long least-recently-used (LRU) buffer queues and are managed by least-recently-used (LRU) mechanism.
由于没有哪一方需要管理内存，确定缓冲区的大小就变得不必要了(因而也不可能存在前面指出的多次执行问题)。
Because no party needs to manage memory, buffer-size identification becomes unnecessary (hence there's no possibility of the multi-execution problem identified earlier).
具体地说，管理员必须定义适当的数据库对象，比如分区组、表空间、缓冲区池等等。
Specifically, an administrator must define appropriate database objects, such as partition groups, table Spaces, buffer pools, and so on.
