Although it is done at a different level here, I wanted to note that mounting a 
filesystem read-only does not necessarily mean the system will not try to write 
to it. This is the case for ext3, for example - when mounted ro, system will 
still reply the journal and do some writes etc.

The patch, however, should take care of that, too, as it is completely different 
place it is made ro.
