No, it didn't. And if you are really sure, please tell me what I did wrong ;).
The problem is in read_node. It calls diskfs_cached_lookup to look up the
directory holding the node because the stat information (inode) is stored in the
directory. The directory needs to be locked, but is already locked in some
cases.
There is another locking problem triggered by writing support, I assume you were
thinking about that one...
I thought I already explained this serveral times...
