problem with inet_ntoa function in LKM

i'm trying my hands on LKMs as part of my project. i have a problem "insmod"ing one of my modules. the module contains an "inet_ntoa" function,which was intended to convert the IP address of the packets(which i receive thru netfilter hook).
when i try to insmod, the error shown isunrecognised type, due to the reason that "inet_ntoa" is not there in /proc/kallsyms file.

i'd like to knw if i can replace "inet_ntoa" with some other function which is ther in kallsyms.
thanks in advance...

Can't find a reference to inet_ntoa (as in the userland function) but there used to be an in_ntoa which was removed in 2.4.19 (ChangeLog) in favour of the NIPQUAD macro.

Don't think it would be a direct drop-in replacement for your function but it probably wouldn't be too hard to fiddle your source to make it work. Have a look here for some example usage in a recent kernel.
