Incompatible use of msleep or schedule_timeout in tasklet? -- Linux general technology-Linux technology and application information. For details, refer to the following section. In ARM + Linux drivers, tasklet is used for interruption, msleep or schedule_timeout is used in tasklet, and usleep is used in user space applications. After running the program, OOPS is displayed, the kernel crashes. If the kernel or application is used independently, the program runs normally. Why cannot we use sleep-related latency functions in both the driver and application? If you want to use it all, is there anything else to solve that problem ??
