[PATCH 0/1] mm/memfd_luo: use KHOSER_PTR for serialized_data checks

[Tarun Sahu <tarunsahu@google.com>]

Use the KHOSER_PTR interface for serialized_data in memfd_luo to
perform type-safe pointer conversions and checks.

I have tried to keep the changes minimal. So only changed
the memfd_luo. Would love the suggestions for if we should be changing
struct liveupdate_file_op_args like the following.

@@ -46,7 +47,7 @@ struct liveupdate_file_op_args {
 	struct liveupdate_file_handler *handler;
 	int retrieve_status;
 	struct file *file;
-	u64 serialized_data;
+	DECLARE_KHOSER_PTR(serialized_data, void *);
 	void *private_data;
 };

Ofcourse, it will require change in liveupdate and luo_file.
