Hi,

I had some problems compiling the ramdisk driver:

gcc -D__KERNEL__ -I/Depot/Sources/2.4.21-rc1/include -Wall -Wstrict-prototypes 
-Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer 
-pipe -mpreferred-stack-boundary=2 -march=i686 -DMODULE -DMODVERSIONS 
-include /Depot/Sources/2.4.21-rc1/include/linux/modversions.h  -nostdinc 
-iwithprefix include -DKBUILD_BASENAME=rd  -c -o rd.o rd.c
rd.c:88: `CONFIG_BLK_DEV_RAM_SIZE' undeclared here (not in a function)
make[2]: *** [rd.o] Error 1
make[2]: Leaving directory `/Depot/Sources/2.4.21-rc1/drivers/block'
make[1]: *** [_modsubdir_block] Error 2
make[1]: Leaving directory `/Depot/Sources/2.4.21-rc1/drivers'
make: *** [_mod_drivers] Error 2

The simple patch below can fix it, though. Is it ok to check against 
CONFIG_BLK_DEV_RAM_SIZE definition and redefine it if not found?
