From 3f3942aca6da351a12543aa776467791b63b3a78 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 15 May 2018 15:57:23 +0200 Subject: proc: introduce proc_create_single{,_data} Variants of proc_create{,_data} that directly take a seq_file show callback and drastically reduces the boilerplate code in the callers. All trivial callers converted over.
