linux创建线程的函数 fork –> do_fork

do_fork的执行线路

graph LR
do_fork --> copy_process --> get_task_pid --> wake_up_new_task --> put_pid

do_fork函数原型

long _do_fork(unsigned long clone_flags,
	      unsigned long stack_start,
	      unsigned long stack_size,
	      int __user *parent_tidptr,
	      int __user *child_tidptr,
	      unsigned long tls);
  • clone_flags
  • stack_start
  • stack_size
  • parent_tidptr
  • child_tidptr
  • tls
