+Subject: [PATCH] transport: protect include and callsite with same conditional
+
+transport.c has the following code block:
+
+  if (!debugfs_p && security_locked_down (LOCKDOWN_DEBUGFS))
+
+Which is protected by the conditional STAPCONF_LOCKDOWN_DEBUGFS.
+
+linux/security.h provides the definition of LOCKDOWN_DEBUGFS, and
+must be included or we have a compilation issue.
+
+The include of security.h is protected by #ifdef CONFIG_SECURITY_LOCKDOWN_LSM,
+which means that in some configurations we can get out of sync with
+the include and the callsite.
+
+If we protect the include and the callsite with the same #ifdef, we can
+be sure that they will be consistent.
+
+Upstream-status: Inappropriate (kernel-devsrc specific)
