Hmmm, I was wrong about the function referenced in fs/proc/root.c. It's proc_unlink()
which is referenced. The following patch simply removes it from the structure
"proc_dyna_dir_inode_operations" in kernel 2.2.17pre19. It works for me, but I repeat
that I don't know if this could break something. Testers welcome.

(also MIME-attached)

Cheers,

Willy
