Abstract

The invention discloses a file operation method of a user space file system and a user space file system. The method includes: a virtual file system receives a file operation request for a target file in the user space file system sent by an application program, and sends the file operation request to the user space file system. It is sent to the target driver module corresponding to the user space file system; the target driver module opens the extension filter to call the instrumentation function corresponding to the file operation request to perform the corresponding file operation on the underlying file system, and according to the operation result, execute the corresponding file operation in the kernel. and the user space daemon obtains the data update result from the shared data area and sends the data update result to the application. According to the technical solution of the present invention, the frequency of data interaction between the user space and the kernel can be effectively reduced, which is beneficial to reducing system overhead.

Description

technical field [0001] The present invention relates to the technical field of file systems, in particular to a file operation method of a user space file system, a user space file system and a computing device. Background technique [0002] FUSE (Filesystem in Userspace, user space file system) is a file system framework implemented in user space, including FUSE kernel module, user space library Libfuse and user program modules. Based on the support of the FUSE kernel module, developers only need to implement specific file operations according to the interface provided by FUSE to implement a file system. [0003] Since the main implementation code of FUSE is located in user space, there is no need to recompile the kernel, which brings many conveniences to developers. However, FUSE has a large performance overhead. The same file operations (such as file search, open, read, write, etc.) have far less overhead and latency on the local system than the FUSE file system, which ...
