Iterating code of /proc/kallsyms calls module_get_kallsym() which grabs
and drops module_mutex internally and returns "struct module *",
module is removed, aforementioned "struct module *" is used in non-trivial
way.
So, grab module_mutex for entire operation like /proc/modules does.
I would still prefer the other solution to avoid exposing "module_mutex"
outside of module.c like this :(
I'll try to send in a patch today for review.
