cache. I'll have to revisit that sometime...
thanks for putting that on your todo list.

I'll queue it for the next release, whenever that is. Typically if nothing
serious breaks in the meantime, I do it about once a month.
If you want to look at all of the objects in a slab represented
as data structures, you're going to have supply the knowledge of
what data structure they are. It's simple enough, just do a "kmem -S"
into a file, delete everything except the object addresses that you're
interested in, insert "struct whatever" in front of each address, save
this is exactly what i did when i have to do work like this by using
gawk, tr, and grep.
the file -- and run it as crash input file.
how to do this? i know crash -i can run a file at beginning. but how to
run command in a file at any moment?
Enter "help input" -- where it talks about "<":
