GMail doesn't make it easy, I'll send a link to a pastebin next time.
Let me know if you'd like me to regenerate the decoded stack.

Hey,
Continuing from this thread earlier today:
* https://marc.info/?t=15488672911&r=1&w=2
We fired up KASAN enabled kernel one one of those machine and this is
what we saw:
$ /tmp/decode_stacktrace.sh
/usr/lib/debug/lib/modules/4.19.18-cloudflare-2019.1.8-1-gcabf55c/vmlinux
linux-4.19.18 <
Eric,
Are you going to propose the change then?
I'm happy to test it out.

Hey,
We've upgraded some machines from 4.19.13 to 4.19.18 and some of them
crashed with the following:

This allows transparent cross-compilation with CROSS_COMPILE.

Hey,
Is it possible to cross-compile bpftool for arm64? I'm trying to do
the same thing we do for perf, but bpftool Makefile doesn't seem to
support CROSS_COMPILE variable, so one needs to pass
CC=aarch64-linux-gnu-gcc as well. Problems do not end there as it
requires EXTRA_LDFLAGS="-lz" too. With
