. A file can have multiple virtual addresses (identified by multiple vm_area_struct) but can have only one physical address (address_space data structure). Each Address_space object has a unique base tree. Motoki is a binary tree that can quickly retrieve the desired data in the base tree as long as the file offset is specified. This data is called dirty data when the page cache data is newer than the data stored in the background. Writeback in the

Special Instructions For those of you who want to write a review after my essay, please note that my blog is written using Markdown, and support for Mathjax mathematical formulas is enabled. If there are two in a comment $ , Mathjax will think that the $ content between the two is a mathematical formula, resulting in a confusing format. If you are sure that your comments are not mathematical formulas, please use \$ escape, thank you. Want to read the series from scratch? Here is the Portal:

Now it seems that the data structure is really the art of art.Multithreading

Linux Partitioning knowledgePrimary partition, extended partition, logical partition1, a hard disk can have up to 4 primary partitions (primary), where one primary partition can be replaced by an extended partition (extend), only one extended partition, within the extended partition can be divided into multiple logical partitions (L).2. If you plan for more than four partitions: the partition combination is 3primary+1extend or 2p+1e or 1p+1e.3, a disk

Because of its price, flexibility, and stability advantages, Linux software has found many users in IT departments or research institutions. Today, companies such as Novell, Red hat and Sun are advocating Linux to the desktop, but the market is still dominated by Microsoft Windows, although it can be seen as a chance for Linu
