From 8bc921220c5db999ddd756fc6d8c23e46d7efd24 Mon Sep 17 00:00:00 2001 From: Alexander Popov Date: Fri, 17 May 2019 22:42:22 +0300 Subject: [PATCH] kconfig: Terminate menu blocks with a comment in the generated config Currently menu blocks start with a pretty header but end with nothing in the generated config. So next config options stick together with the options from the menu block. Let's terminate menu blocks in the generated config with a comment and a newline if needed. Example: ... CONFIG_BPF_STREAM_PARSER=y CONFIG_NET_FLOW_LIMIT=y # # Network testing # CONFIG_NET_PKTGEN=y CONFIG_NET_DROP_MONITOR=y # end of Network testing # end of Networking options CONFIG_HAMRADIO=y ...
