From c3506372277779fccbffee2475400fcd689d5738 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 10 Apr 2018 19:42:55 +0200 Subject: proc: introduce proc_create_net{,_data} Variants of proc_create{,_data} that directly take a struct seq_operations and deal with network namespaces in ->open and ->release. All callers of proc_create + seq_open_net converted over, and seq_{open,release}_net are removed entirely.
