Not an official patch, but as the symbol was introduced into
mm/filemap.c
and is used widely through linux/mm.h, I guess it should simply be
exported.

	Also rd.o if you have that compiled as a module.

Why are you (still) using 2.4.14-preX? Current stable version is 2.4.22 
and 2.4.23-preX is under development.

Anyway, grep for "unlock_page" in all .c files, find out if the .o of it 
is built and if the symbol is exported with EXPORT_SYMBOL.

BTW. Did you save the .config file and ran "make mrproper" before 
building? It is very likely that after patching up in a "used" tree, the 
rebuild is not going entirely correctly.

Regards,

Bas.

This message shouldn't prevent the new modules from being installed.
This comes from `depmod` which is creating /lib/modules/`uname
-r`/modules.dep. When you boot the new kernel, the boot-script
will (probably) execute `depmod -a`, fixing the problem. Your
new kernel probably has unlock_page exported. The older one
probably didn't.

Tty it. It should work okay.
