From 2efaecaf9603bed6999bac0869dd2ae7edf828ba Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Mon, 1 Mar 2021 17:05:08 -0500 Subject: [PATCH] fs: dlm: fix debugfs dump [ Upstream commit 92c48950b43f4a767388cf87709d8687151a641f ] This patch fixes the following message which randomly pops up during glocktop call: seq_file: buggy .next function table_seq_next did not update position index The issue is that seq_read_iter() in fs/seq_file.c also needs an increment of the index in an non next record case as well which this patch fixes otherwise seq_read_iter() will print out the above message.
