- - support asynchronous operation -- add a per-fs 'reserved_space' count,
-   let each outstanding write reserve the _maximum_ amount of physical
-   space it could take. Let GC flush the outstanding writes because the
-   reservations will necessarily be pessimistic. With this we could even
-   do shared writable mmap, if we can have a fs hook for do_wp_page() to
-   make the reservation.
- - disable compression in commit_write()?
- - fine-tune the allocation / GC thresholds
- - chattr support - turning on/off and tuning compression per-inode
- - checkpointing (do we need this? scan is quite fast)
- - make the scan code populate real inodes so read_inode just after 
-	mount doesn't have to read the flash twice for large files.
-	Make this a per-inode option, changeable with chattr, so you can
-	decide which inodes should be in-core immediately after mount.
- - test, test, test
- - NAND flash support:
-	- almost done :)
-	- use bad block check instead of the hardwired byte check
- - Optimisations:
-   - Split writes so they go to two separate blocks rather than just c->nextblock.
-	By writing _new_ nodes to one block, and garbage-collected REF_PRISTINE
-	nodes to a different one, we can separate clean nodes from those which
-	are likely to become dirty, and end up with blocks which are each far
-	closer to 100% or 0% clean, hence speeding up later GC progress dramatically.
-   - 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 size from jffs2_raw_node_frag. 
-1. __jffs2_flush_wbuf() has a strange 'pad' parameter. Eliminate.
-2. get_sb()->build_fs()->scan() path... Why get_sb() removes scan()'s crap in
-   case of failure? scan() does not clean everything. Fix.
