Re: query_modules syscall gone? Any replacement?

[iSteve <isteve@rulez.cz>]

Drat, that's a pity, the interface seemed pretty neat and usable (from 
my rather linux-kernel-newbie point of view, anyway:), especially neater 
than parsing a file.

Why did the query_module get removed, by the way? (I searched lkml, but 
lkml.org search on 'query module' or 'query_module' didn't really give 
me any relevant hits).
