直接获取/ proc的proc_dir_entry

Question

I could use following code to get the /proc entry, but how to get the /proc entry directly? Any function in the kernel to do this directly(without creating one dummy sub-entry)?

  new_proc = proc_create("dummy", 0644, 0, &fileops_struct);
  root = new_proc->parent;

Answer 1

I haven't found a function, but you might access proc_root directly.

It is located in fs/proc/root.c and should be accessible from outside.
