Can you please explain why you are removing the error handling when you are unwinding the registration loop? > int __init atm_proc_init(void) > { > - static struct atm_proc_entry *e; > - int ret; > - > atm_proc_root = proc_net_mkdir(&init_net, "atm", init_net.proc_net); > if (!atm_proc_root) > - goto err_out; > - for (e = atm_proc_ents; e->name; e++) { > - struct proc_dir_entry *dirent; > - > - dirent = proc_create(e->name, 0444, > - atm_proc_root, e->proc_fops); > - if (!dirent) > - goto err_out_remove; > - e->dirent = dirent; > - } > - ret = 0; > -out: > - return ret; > - > -err_out_remove: > - atm_proc_dirs_remove(); > -err_out: > - ret = -ENOMEM; > - goto out; > + return -ENOMEM; > + proc_create_seq("devices", 0444, atm_proc_root, &atm_dev_seq_ops); > + proc_create("pvc", 0444, atm_proc_root, &pvc_seq_fops); > + proc_create("svc", 0444, atm_proc_root, &svc_seq_fops); > + proc_create("vc", 0444, atm_proc_root, &vcc_seq_fops); > + return 0; > } These proc entries could fail to register with -ENOMEM if for no other reason. Can you justify the removal of the error handling? Can you please at least mention that removal in your change description and explain why it is reasonable. As it sits this is not a semantics preserving transformation, and the difference is not documented. Which raises red flags for me.
