本文将介绍内核(kernel version 4.14)是在何时如何将写入的数据回写到磁盘。核心数据结构初始化 回写机制借助了Linux中工作队列来完成，在内核启动的时候，系统会使用alloc_workqueue函数申请一个用于回写的工作队列。具体实现在函数default_bdi_init中。// /mm/backing-dev.cstaticint_
The initial Linux kernels had a very simple numbering system. The first, which was released by Torvalds in September 1991, was designated 0.01. This was followed the next month by the 0.02 kernel. The current version numbering system began with the kernel 1.0, which was released in March 1994...
