Well, I never said that kernfs was Bad; I just said that there are people
who are likely to want symbol table access without adding kernfs.

: about having the linker in the kernel?

Using LKMs without having /usr available; building LKMs as
position-independent code ("shared objects" in the kernel).  Two uses I can
think of...

What a /dev/ksyms woud be useful for, of course, is the ability to find
kernel symbols when the kernel file is not available, and to find kernel
symbols located inside LKMs.
