max_threads = mempages / (THREAD_SIZE/PAGE_SIZE) / 8;
- init_task.rlim[RLIMIT_NPROC].rlim_cur = max_threads/2; - init_task.rlim[RLIMIT_NPROC].rlim_max = max_threads/2; + /* + * we need to allow at least 10 threads to boot a system + */ + init_task.rlim[RLIMIT_NPROC].rlim_cur = max(10, max_threads/2); + init_task.rlim[RLIMIT_NPROC].rlim_max = max(10, max_threads/2);
why not simply:
max_threads = mempages / (THREAD_SIZE/PAGE_SIZE) / 8;
+ /* we need to allow at least 20 threads to boot a system */ + if (max_threads < 20) + max_threads = 20; + init_task.rlim[RLIMIT_NPROC].rlim_cur = max_threads/2; init_task.rlim[RLIMIT_NPROC].rlim_max = max_threads/2;
i think we're going to see more kernel threads with 2.5 than we did with 2.4; let's be safer.
