You can pick the whole dir of ext2, rename it to another name foo. Then

need to change back some FOO or foo to EXT2 or ext2 because they are not
in the ext2 dir. These are general stuff, like bit operations that you
may not want to change at all. Other small changes that may occur are
also trivial.
I dit that changing ext2 to extp.
You may have to change this depending on the version of the kernel.
for f in $(ls *.c *.h Makefile); do
echo $f
sed -i \
-e s/ext2/extp/g \
-e s/EXT2/EXTP/g \
-e s/extp_find_next_zero_bit/ext2_find_next_zero_bit/g \

/usr/src/linux/include/linux and rename all files ext2* to extp*. Then
replace refs to #include <linux/* > to #include "*".

Other way of doing is,
- compile kernel without ext2 support, i.e. set CONFIG_EXT2_FS as n. [probably others too, you can experiment CONFIG_EXT2_FS_XATTR, CONFIG_EXT2_FS_POSIX_ACL, CONFIG_EXT2_FS_SECURITY ]
- Then the kernel compiled wont have ext2 as its part.
- Then compile your ext2 directory as module. To do this you'll need to edit Makefile, replace CONFIG params by m. e.g.
- replace obj-$(CONFIG_EXT2_FS) += ext2.o by obj-m += ext2.o
But make sure that your disk file-system that you are using is other than ext2, because it no more will be recognized.
