+Subject: [PATCH] root_commands: prevent linker error when plugins are disabled
+
+This commit fixes compilation issue with disabled plugin support
+(./configure --plugins=0), where get_plugins function is unavailable.
+The problem has been introduced with addition of new 'plugins info'
+subcommand, where get_plugins is used in cmd_plugins_info function,
+which should be conditionally available only if WITH_PLUGINS is defined.

+Fixes: 6908ab747d1e ("Add 'plugins info' subcommand, only show plugin details there")
