From a53fb69baa035f181c3fe256ed3a0d70c4ec9647 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 26 Jul 2023 14:59:22 -0700 Subject: ocfs2: use regular seq_show_option for osb_cluster_stack While cleaning up seq_show_option_n()'s use of strncpy, it was noticed that the osb_cluster_stack member is always NUL-terminated, so there is no need to use the special seq_show_option_n() routine. Replace it with the standard seq_show_option() routine.
