From: Alexander Aring <aahringo@redhat.com>
[ 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.
