A developer goes to the warning site: static int __xlate_proc_name(const char *name, struct proc_dir_entry **ret, const char **residual) { const char *cp = name, *next; struct proc_dir_entry *de; int len; de = *ret; if (!de) de = &proc_root; while (1) { next = strchr(cp, '/'); if (!next) break; len = next - cp; for (de = de->subdir; de ; de = de->next) { if (proc_match(len, cp, de)) break; } if (!de) { WARN(1, "name '%s'\n", name); return -ENOENT; } cp += len + 1; } *residual = cp; *ret = de; return 0; } and there's no hint whatsoever to tell him what the warning means, nor how to fix it. Please send a patch adding a nice comment to __xlate_proc_name(). Then perhaps the DVB guys have a chance of fixing this bug.
