Well, the culprit of this problem might be syz_execute_func().

Then, blacklisting specific syscalls/arguments might not work.
We will need to guard specific paths on the kernel side using
some kernel config option...
Anyway, Andrew, will you send this patch to linux-next.git ?
syzbot would identify which syz_execute_func() call is triggering
this problem.
