The put_user function moves the value that the kernel variable (var) specifies into the user-space address (PTR). The functions return zero on success.
put_user函数则将内核变量(var)指定的值移动到用户空间地址(ptr)。
You examined some important kernel parameters, what they do, and how to tune them, including how to make the best use of the variable page size support.
研究了一些重要的内核参数、它们的作用以及如何对它们进行调优，包括如何最适当地使用可变页面大小支持。
Once you have installed this package, make sure that /opt/cross/bin is part of your $PATH environment variable so the tools in the package will be accessible during the kernel build process.
安装完这个程序包后，确保您的 $PATH环境变量中有 /opt/cross/bin，以使得在内核编译过程中可以使用这个程序包中的工具。
By setting this variable, the linker assumes that a 2.4 kernel is running along with the older LinuxThreads model.
通过设置这个环境变量，连接器将认为2.4内核运行旧的LinuxThreads模型。
In the Linux kernel, time is measured by a global variable named jiffies, which identifies the number of ticks that have occurred since the system was booted.
在Linux内核中，时间由一个名为jiffies的全局变量衡量，该变量标识系统启动以来经过的滴答数。
The call begins in ./linux/kernel/printk.c in the printk function, which calls vprintk (in the same source file) after resolving the variable-length arguments using va_start.
这个调用从./linux/kernel/printk.c 中的printk函数开始，它会在使用 va_start解析可变长度参数之后调用vprintk（在同一个源文件）。
This paper gives existence and uniqueness condition of solutions of the integral equation with variable separable kernel, and it's elementary solutions.
本文给出了具有变量可分离核的积分方程解的存在条件和初等求解法。
With regionalized variable as its kernel and theory base, the method is a kind of mathematical geological method using spatial correlation and variation functions as its basic tools.
该方法是以区域化变量为核心和理论基础，以空间相关和变异函数为基本工具的一种数学地质方法。
