SubjectRe: query_modules syscall gone? Any replacement?
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).
