Re: [PATCH] panic: Don't print redundant backtraces on oops

it?
I think the two problems are not related. My problem was that only one
CPU should execute panic. Andi's problem is that one (or more oops)
messages are scrolled away by a subsequent panic.
Yes it's just for making panic less chatty.
But I am not sure if Andi's patch solves all his problems. What e.g.
about panic_on_oom? Don't we have the same problem here?
Yes, it only solves it for this specific -- but common -- case. Or at
least it was a case
that annoyed me and prompted me to write the patch :)
I had a patch some time ago for a xpanic() where the caller could pass
in additional
flags, including one to disable the backtrace. But that was a much
larger patch,
this was a simpler alternative.
