Embodiment Construction
[0022] The technical solution of the present application will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only some structures related to the present application are shown in the drawings but not all structures.
[0023] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processing, many of the steps may be performed in parallel, concurrently, or simultaneously. Additionally, the order of steps may be rearranged. The process may be terminated when its operations are complete, but may also hav...

The embodiment of the present application discloses a block device access tracking method, device, storage medium and terminal. The method includes: when a preset block device access event is triggered, if it is determined that there is a preset program code written based on a preset virtual machine before the function to be called corresponding to the preset block device access event in the kernel space, then by The preset program code obtains the block device access information corresponding to the function to be called, and stores the block device access information in a storage format corresponding to the preset virtual machine for reading by the user space. By adopting the above technical solution, the embodiment of the present application can use the preset program code written based on the preset virtual machine implemented in the kernel space to obtain and store block device access information for the user space to read, which can reduce the number of kernel space and user access information. Space interaction reduces the burden of block device access tracking on the system and improves system stability.
Description
technical field [0001] The embodiments of the present application relate to the technical field of terminals, and in particular to a block device access tracking method, device, storage medium and terminal. Background technique [0002] At present, in the operating system of the terminal, access to various files is relatively frequent, and access to files will also generate access to block devices. How to optimize access to block devices is an important part of the system optimization topic. [0003] When researching the optimization of block device access, it is usually necessary to track the block device access to understand the relevant information when the block device is accessed. However, existing document tracking schemes are still not perfect and need to be improved. Contents of the invention [0004] Embodiments of the present application provide a block device access tracking method, device, storage medium, and terminal, which can optimize a block device access ...
