I wish the LKCD folks never put that thing in there to begin with.
Without thinking about it, I tested the patch by simply doing this:
$ crash vmlinux vmcore > /tmp/output
and of course it doesn't even work in that case -- which would seem
to be as desirable as doing it for individual commands.
I would accept a patch that removes the function entirely.
Would anybody object to that?
Dave
I prefer it removed, such a patch will be posted later today unless anyone objects before
I post.
Thank you,
