[probably others too, you can experiment CONFIG_EXT2_FS_XATTR, CONFIG_EXT2_FS_POSIX_ACL, CONFIG_EXT2_FS_SECURITY ] 2. Then the kernel compiled wont have ext2 as its part. 3. Then compile your ext2 directory as module. To do this you'll need to edit Makefile, replace CONFIG params by *m*. e.g. 4. replace *obj-$(CONFIG_EXT2_FS) += ext2.o* by *obj-m += ext2.o* Now each time you can make changes to ext2 module and compile it as a module and insmod it. I have tried this and it works. But make sure that your disk file-system that you are using is other than ext2, because it no more will be recognized. - Sunil .
