Problems solved by technology

[0006] Second, in order to adapt to the compatibility of multiple file systems, the existing file system has a complex structure and a large scale
[0007] Third, it is not convenient for cross-platform portability of the file system
At the same time, because this structure adds new content on the basis of the original structure, the size of the entire kernel is further increased, which is not conducive to the use of resource-constrained systems such as embedded systems.
At the same time, in the process of porting the file system across operating system platforms, this application is no different from the existing Linux standard file system, both of which contain VFS units, and porting is still very difficult
Due to different operating system platforms, the upper and lower interfaces of the file system are also different. It is very difficult to extract the Linux interface from the non-Linux system file system and access the Linux system. This invention does not completely solve the above problems.

Abstract

The related file system of an OS comprises: an interface conversion unit on entrance, a management unit, a physical file system unit, a top drive unit, and an interface conversion unit on exit; all connected in turn. This invention reduces VFS unit in Linux standard file system and kernel size, can be used to process different custom special affairs, and realizes cross-OS transplant.

Description

technical field [0001] The present invention relates to a file system under an operating system, and more specifically, the present invention relates to a file system with enhanced functions and an operating system with the file system of the present invention. The invention also relates to a method for constructing and enhancing the function of the file system. Background technique [0002] In a computer system, a file is the logical organization and presentation of data. Usually, when accessing data in a specific file, the file can be displayed in a recognizable logical form only through the positioning and organization of the file system. In the prior art, an operating system can generally support multiple different physical file system units. For example, the physical file systems supported by the Linux operating system (Linux is a registered trademark or trademark of Linus Torvalds in the United States and other countries) include ext2, ext3, udf, jfs, etc. In order t...
