Two things:
=== 1. shm.c does not compile:
gcc -D__KERNEL__ -I/usr/src/linux/include -D__SMP__ -Wall -Wstrict-prototypes -O 2 -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -DCPU=586 -march=i586 -fno-strict-aliasing -c -o shm.o shm.c shm.c:142: `THIS_MODULE' undeclared here (not in a function) shm.c:142: initializer element is not constant shm.c:142: (near initialization for `shm_fs_type.owner') make[2]: *** [shm.o] Error 1 make[2]: Leaving directory `/u/usr/src/linux-2.3/ipc' make[1]: *** [first_rule] Error 2 make[1]: Leaving directory `/u/usr/src/linux-2.3/ipc' make: *** [_dir_ipc] Error 2
Adding "#include <linux/module.h>" helps this but I am not sure if this is a right approach.
=== 2. If ide driver is configured as module, image does not link: .... -o vmlinux fs/fs.o: In function `msdos_partition': fs/fs.o(.text+0x1fab5): undefined reference to `ide_xlate_1024' fs/fs.o(.text+0x1fae5): undefined reference to `ide_xlate_1024' fs/fs.o(.text+0x1fb6e): undefined reference to `ide_xlate_1024' make: *** [vmlinux] Error 1
This is because in fs/partitions/msdos.c ide_xlate is referred if any of CONFIG_BLK_DEV_IDE and CONFIG_BLK_DEV_IDE_MODULE is defined, while ide-geometry.o is not inlcuded in the kernel image unless CONFIG_BLK_DEV_IDE is defined. If you modify Makefile and drivers/Makefile to include ide-geometry.o in the kernel, you notice that ide-geometry has some unresolved symbols from ide.c...
