Before this patch I had a vmcore that would segfault with 'bt -a',
with backtrace as in
https://github.com/crash-utility/crash/issues/105#issuecomment-1017176451
After this patch the segfault is gone.
Thank you Dave, for testing.
Lianbo, please add the tag when you merge this.
FWIW, I saw was some new warnings with the vmcore but may be expected:
WARNING: cannot determine starting stack frame for task ffff809920692100
WARNING: cannot determine starting stack frame for task ffff80992068ee00
WARNING: cannot determine starting stack frame for task ffff80992069ed00
WARNING: cpu 4: cannot find NT_PRSTATUS note
WARNING: cpu 5: cannot find NT_PRSTATUS note
WARNING: cpu 6: cannot find NT_PRSTATUS note
WARNING: cpu 7: cannot find NT_PRSTATUS note
WARNING: cpu 8: cannot find NT_PRSTATUS note
WARNING: cpu 9: cannot find NT_PRSTATUS note
WARNING: cpu 10: cannot find NT_PRSTATUS note
WARNING: cpu 11: cannot find NT_PRSTATUS note
I cannot try the patch, but if those warnings are for offline cpus,
they are expected.
Thanks,
Kazu
