I just found this thread on "http://mail.nl.linux.org/kernelnewbies/2003-09/msg00285.html" and have an exactly opposite question. How do I remove a kernel thread in kernel mode ? I write a C-function in one of the Linux source files and create a kernel thread by invoking kernel_thread() to run the function, like: "kernel_thread(a1, NULL, CLONE_FS | CLONE_FILES | CLONE_SIGNAL);" Function a1 simply invokes printk() to output some message on console. I invoke do_exit(0); at the end of a1, but a1's task_struct still exists in in task_struct list after its execution. How do I remove it a1's task_struct upon its completion? I thought explicitly invoke do_exit() ensures the removal of task_struct? -- Kernelnewbies: Help each other learn about the Linux kernel.
