Thomas, Roland and me agreed on the interface change.  This needs to be implemented now.  The read side you already implemented.  I will make this task depend on that patch.

I've tried changing the diskfs_node_update interface and its callers. This is a lot of work, also the callers of some callers have to be changed (diskfs_file_change for example).

Another solution I thought about can't work. That solution was using a rwlock to lock individual directory entries. This is not possible because the directory needs to be mmapped and a lock is required when creating a pager for a file. (See diskfs_get_filemap).
