I like it.  With kbuild 2.5 the generation of ext2_all.c (I prefer
ext2_static.c) can be automated.

objlink(ext2.o balloc.o bitmap.o dir.o file.o fsync.o ialloc.o inode.o ioctl.o
        namei.o super.o symlink.o)
select(CONFIG_EXT2_FS ext2.o)
make_static(ext2)

make_static(xxxx), which does not exist yet -

* Checks if CONFIG_MAKE_STATIC is set.
* Takes the objlink information from the kbuild 2.5 database.
* Automatically creates xxxx_static.c as a series of #include
  statements for the source files derived from objlink.
* Replaces the objlink data with objlink(xxxx.o xxxx_static.o).
* Compiles xxxx_static.c with -DXXXX_STATIC=static.

The code that is normally linked into xxxx.o has to be manually changed
to add XXXX_STATIC before a make_static(xxxx) command can be added.
