From 3617d9496cd92dcca4d0893191d95554590d8d9f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 13 Apr 2018 20:38:35 +0200 Subject: proc: introduce proc_create_net_single Variant of proc_create_data that directly take a seq_file show callback and deals with network namespaces in ->open and ->release. All callers of proc_create + single_open_net converted over, and single_{open,release}_net are removed entirely.
