wangzijie 0ce9398aa0 proc: fix type confusion in pde_set_flags() ... Commit 2ce3d282bd ("proc: fix missing pde_set_flags() for net proc files") missed a key part in the definition of proc_dir_entry: union { const struct proc_ops *proc_ops; const struct file_operations *proc_dir_ops; }; So dereference of ->proc_ops assumes it is a proc_ops structure results in type confusion and make NULL check for 'proc_ops' not work for proc dir. Add !S_ISDIR(dp->mode) test before calling pde_set_flags() to fix it.
