No.  It needs *both* the vmlinux file and the vmcore file in order to read
kernel
virtual memory, so just having a kernel virtual address is insufficient.

So it's a chicken-and-egg situation.  This particular --osrelease option is used
to determine *what* vmlinux file would be required for an actual crash analysis
session.

Ok, that makes sense. I could've used that explanation when reviewing
the documentation. Do you mind skimming through this:

https://lkml.kernel.org/r/20190111145650.GG4729@zn.tnic

in case we've missed explaining relevant usage - like that above - of
some of the vmcoreinfo members?

Yeah, I've been watching the thread, and the document looks fine to me.
It's just that when I saw the discussion of this one being removed that
I felt the need to respond...  ;-)

Thank you for explaining this issue.
