From fddda2b7b521185f3aa018f9559eb33b0aee53a9 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 13 Apr 2018 19:44:18 +0200 Subject: proc: introduce proc_create_seq{,_data} Variants of proc_create{,_data} that directly take a struct seq_operations argument and drastically reduces the boilerplate code in the callers. All trivial callers converted over.
