Help my please. Question about "interactive" clone and waitpid syscalls.
Describe. Process was create five a process using clone syscall. Two clone calling with CLONE_THREAD, other three without CLONE_THREAD. After then process was calling waitpid(getpid, &status, __WNOTHREAD), then it must not checkout process, that was created by clone with CLONE_THREAD, is not it? Questions. Where define thread_info struct? Where define list_head struct? I right understand, that in kernel/fork.c, copy_process() function add process to thread group? //1171 string number list_add_tail_rcu(&p->thread_group, &p->group_leader->thread_group); And do_wait contain next_thread too, but waitpid(getpid(), &status, __WALL) it is good, but really waitpid syscall not return info about thread, because return error "no child process". I sure that is not right, or I delusion? I waiting from waitpid info about thread, but not error.
