loop Device doesn't work in kernel 2.4.14

Hello,

I have detected that the loop device mechanism can't be
used any longer in kernel version 2.4.14. I have compiled
the kernel with minimum features (ext2, initrd, ramdisk) compiled
into the kernel. The rest is all modules.

# cat /proc/version
Linux version 2.4.14 (root@pcls03) (gcc version 2.95.3 20010315 (SuSE)) #2 Wed Nov 7 11:34:01 CET 2001

# mount -o loop /tmp/DISK /mnt -v
mount: Could not find any loop device, and, according to /proc/devices,
       this kernel does not know about the loop device.
       (If so, then recompile or `insmod loop.o'.)

# modprobe -v loop
/sbin/insmod /lib/modules/2.4.14/kernel/drivers/block/loop.o
Using /lib/modules/2.4.14/kernel/drivers/block/loop.o
Symbol version prefix ''

/lib/modules/2.4.14/kernel/drivers/block/loop.o: insmod loop failed

# find /usr/src/linux-2.4.14 -type f -name '*.[ch]' |xargs grep deactivate_page
/usr/src/linux-2.4.14/drivers/block/loop.c:             deactivate_page(page);
/usr/src/linux-2.4.14/drivers/block/loop.c:     deactivate_page(page);

# depmod -ae
depmod: *** Unresolved symbols in /lib/modules/2.4.14/kernel/drivers/block/loop.o
depmod:         deactivate_page
depmod: *** Unresolved symbols in /lib/modules/2.4.14/kernel/drivers/net/wan/comx.o

depmod: *** Unresolved symbols in /lib/modules/2.4.14/kernel/drivers/telephony/ixj_pcmcia.o
depmod:         register_pccard_driver
depmod:         unregister_pccard_driver
depmod:         CardServices

There seems to be a problem with the routine deactivate_page, which is no longer present
in the 2.4.14 kernel but is used somehow in the loop device code.
