These functions which are giving u "unresolved symbols" error...work
only well in user mode applications....
As, rightly pointed out by somebody in this mailing list...only
functions that are there in /proc/ksyms can be
called by ur kernel module.
However, to call the user space functions...u have to link the file in
which these functions are present with ur
kernel module...
i have tried it..it works fine...
For eg: kernel.c : ur kernel module
user.c : the file which contains the functions which
need to be called from kernel module...
try this:
gcc -o kernel.o -nostartfiles -wl,-r kernel.c user.o
i hope this might help...

puja
