Re: use of EXPORT_SYMBOL()

[Sabyasachi Pradhan <spradhan@xxxxxxxxxxxxx>]

Hi,

    To compile the kernel properly I had to make a change to the Makefile
in linux/fs/ to add a new entry super.o to extern-obj's. I was checking
the exported symbols in my kernel use /proc/ksyms and just wanted to know
what the string appearing before the symbol signify, is it the address in
memory ? Can I use the exported synbol directly in my program or do I have
to make any more changes ? Thanks.

regards,
