After kzalloc_obj()\nsucceeds in nlm_lookup_file(), the freshly allocated nlm_file is not\nyet inserted into nlm_files[]. The nlm_do_fopen() failure path jumps\nto out_unlock, which releases nlm_file_mutex and returns without\nfreeing the allocation, so each failure leaks one nlm_file.\n\nRoute the failure through out_free so kfree() runs before the\nfunction returns."
