Or junk the > code. This looks very wrong. ELF-FDPIC is currently using kobjsize() so that it can expand the heap/stack segment to fill up the entirety of its allocation. It's probably worth dropping that, though. NOMMU mmap() is using kobjsize()/ksize() to keep track of the number of bytes allocated and the amount of dead space. We can probably ditch that too. However, fs/proc/task_nommu.c uses kobjsize() quite a bit to determine how much metadata space a process is carrying around. We could just use sizeof(), I suppose, and not bother calculating the slack.
