This is bug, kernel does not require <source> for MS_REMOUNT, so the
current mount(8) behavior is too restrictive.
For standard use-case we want to read mtab (/proc/self/mountinfo) to
gather all mount options for the mount syscall, but this behavior
should be optional.
Fixed by commit 01966ce852ac6c46e7e35a8e4f981dea88620ff8,
