    - Furthermore, in the case where it could be copied intact we don't even need
      to call iget() for it -- if we use (raw_node_raw->flash_offset & 2) as a flag
      to show a node can be copied intact and it's _not_ in icache, we could just do
      it, fix up the next_in_ino list and move on. We would need a way to find out
      _whether_ it's in icache though -- if it's in icache we also need to do the 
      fragment lists, etc. P'raps a flag or pointer in the jffs2_inode_cache could

+     help. (We have half of this now.)
    - Stop keeping name in-core with struct jffs2_full_dirent. If we keep the hash in 
      the full dirent, we only need to go to the flash in lookup() when we think we've
      got a match, and in readdir(). 
    - Doubly-linked next_in_ino list to allow us to free obsoleted raw_node_refs immediately?
    - Remove totlen from jffs2_raw_node_ref? Need to have totlen passed into
 	jffs2_mark_node_obsolete(). Can all callers work it out?
-   - Don't check data CRC on node scan during mount. We don't really need to know 
-	yet. This means we can't build up node fragment lists, and hence can't 
-	build accurate clean/dirty information. But we don't _need_ that for reading,
-	only for writing. And in fact we don't even need it for writing until we 
-	start to need GC.
+   - Remove size from jffs2_raw_node_frag.
