+ - disable compression in commit_write()? Or at least optimise the 'always write
+	whole page' bit.
+ - fix zlib. It's ugly as hell and there are at least three copies in the kernel tree
+ - 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, changable with chattr, so you can
+	decide which inodes should be in-core immediately after mount.
+ - stop it depending on a block device. mount(8) needs a change for this.
+ - make it work on NAND flash. We need to know when we can GC
+	deletion dirents, etc. And think about holes/truncation. It can
+	all be done reasonably simply, but it need implementing.
+ - NAND flash will require new dirent/dnode structures on the medium with
+	ECC data in rather than just the CRC we're using ATM.
+ - test, test, test
