Method, system and device for upgrading kernel state client and storage medium

Abstract

The invention discloses a method, system and device for upgrading a kernel state client and a storage medium. The method includes the steps of acquiring respective identification information of a substituting function and a substituted function input from the outside; combining the respective identification information of the substituting function and the substituted function into a substitution event; and adding a substitution event to a global event linked list of a kernel state module for the kernel state module to substrate the substituted function in itself with the substituting functionwhen executing the global event linked list. According to the method for upgrading the kernel state client, the respective identification information of the substituting function and the substituted function is combined into the substitution event, the substitution event is added into the global event linked list of the kernel state module, the kernel state module triggers the substitution event by means of the global event linked list, and since a front-end application does not need to stop running when the kernel state module executes the global event linked list, the applicability of the kernel state update method is improved to some extent.

Description

technical field [0001] The present invention relates to the technical field of distributed storage, and more specifically, relates to an upgrade method, system, device and storage medium of a kernel state client. Background technique [0002] With the development of storage technology, the application of distributed storage is becoming more and more extensive. However, the IO latency of distributed storage is high. In order to reduce the IO latency, the existing distributed file system uses a kernel-mode client to improve IO efficiency. [0003] However, when upgrading the function of the kernel mode client, it is necessary to stop the front-end application first, and then reload the kernel mode module. The kernel mode module mentioned here encapsulates the functions to be run and the global event list, which is not suitable for those who do not allow the front-end application to stop. The distributed file system in the kernel state makes the applicability of the existing k...
