内核日志(dmesg和alog)。
The kernel log messages are then stored in /var/log/kern.log (among other configured files).
然后这些内核日志消息会存储在 /var/log/kern.log（及其他配置的文件）。
The string passed into printk is then copied into the kernel log buffer using a special function that manages the bounds of the ring (emit_log_char).
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。
It then looks at movement of log data from the kernel into user space.
然后，本文介绍了日志数据从内核到用户空间的移动过程。
All UNIX and Linux systems have a log that is actually part of the kernel.
所有unix和Linux系统的日志实际上是内核的一部分。
The kernel trace hooks call functions in the device driver code, which log the information provided by the kernel trace hooks in pinned buffers.
内核追踪挂钩调用设备驱动程序代码中的函数，那些函数将内核追踪挂钩在固定缓冲区（pinned buffer）中给出的信息记录下来。
Although the first two command types perform no action within the kernel, the rest are used to read log messages or control aspects of logging.
虽然前面两个命令类型不会对内核进行任何操作，但是其余命令则是用于读取日志消息或控制日志。
With these simple algorithms for user space and kernel-level code, you now have the ability to detect, log, and respond to the full range of physical input from the user.
通过使用针对用户空间和内核级代码的这些简单算法，现在能够检测、记录和响应来自用户的各种物理输入。
The kernel allows each message to be classified with a log level (one of eight that define the severity of the particular message).
内核允许每一个消息根据日志级别(定义不同消息重要必的八种级别之一)来分类。
Finally, the article explores the target of kernel-based log data: the log management framework in user space with rsyslog.
最后，本文还介绍了基于内核的日志数据的目标：用户空间中使用rsyslog进行日志管理。
At last, the kernel common module, file of control rule and log file are designed, and the next-step work of system is viewed.
另外，本文还对核心公用模块、控管规则文件、日志文件进行了设计，对今后的工作做出了进一步的展望。
This paper proposes a kernel function - hierarchical log-polar matching kernel which making use of the feature spatial information for building classification in remote sensing images.
提出了一种利用图像特征空间信息的核函数——层次对数极坐标匹配核，用于遥感图像建筑物目标的分类。
