3 - Make symlinks work properly.
5 - Fill in the skeleton gcthread.c so it actually does something.
7 - Check and possibly fix locking of icache mangling in fs-ecos.c
9 - Check that os-ecos.h defines 'spin_lock()' to something appropriate.
11 - Fix unmount of root file system after chdir().
13 - Fix atomicity of renames. Why was the unlink added before rename?
15 - Further cleanup -- should the functions in dir-ecos.c take 'struct
16 dirsearch' instead of various components thereof, or should each of
17 those functions just be moved inside its only caller in fs-ecos.c?
19 - Improve mount time by using pointer directly into flash chip instead
20 of jffs2_flash_read() for the initial scan -- look at the #ifdef
21 __ECOS bit in scan.c for details.
23 - Reduce memory usage. There are fields marked for possible removal in
24 struct _inode, and there's the __totlen field in struct
25 jffs2_raw_node_ref as discussed recently.
