If you are using kernel 2.6.24 or below you can specify the prototype:
extern int get_filesystem_list(char *);
It does not look like this function was intended for general use, so
be careful.

I need the list of file systems registered on the system,
get_filesystem_list() does the same.
I have included the file <linux/fs.h> as well. Why is it not
working and how to make it work?
get_filesystem_list() is not exported for use by modules. Probably
just because noone needs it...
For your own personal use, you can just export if from your kernel
yourself. Add a
EXPORT_SYMBOL(get_filesystem_list);
directly after the closing brace of get_filesystem_list() (that
location is just convention, technically anywhere would be fine) and
recmpile the kernel. After reboot, get_filesystem_list() is
available to modules.
