我们知道,每个进程在kernel中都有一个对应的task_struct与之对应,而通过task_struct可以间接地获得一个fd_array[]数组,表示当前进程已经打开的文件,每一个元素都是一个文件描述符的值,只有通过这个fd_array[x]才能获取当前进程打开的文件的struc file*,而rcu_assign_pointer(fdt->fd[fd], NULL)的作用就在于将将...
也是 Linux kernel 中最为庞杂的子系统, 没有之一.截止 4.2 版本,内存管理子系统(下简称 MM)所有平台独立的核心代码(C文件和头文件)达到11万6千多行,这还不包括平台相关的 C 代码, 及一些汇编代码;与之相比,调度子系统的平台独立的核心代码才2万8千多行....

Linux is an open-source operating system based on UNIX. It was named after the founder “Linus Torvalds”. He introduced Linux with the primary goal to offer an operating system at a free or very reasonable price for users. It is based on the Linux kernel and is compatible with different...
Hotspot supports a very powerful way of doing wait-time analysis, or off-CPU profiling. This analysis is based on kernel tracepoints in the linux scheduler. By recording that data, we can find the time delta during which a thread was not running on the CPU, but instead was off-CPU. The...
There is a simple test suite insh tests/. The test suite requires root to run and access to mce-inject and a kernel with MCE injection supportCONFIG_X86_MCE_INJECT. It will kill any running mcelog daemon. Run it withsh make test. ...
