The following commit is breaking dwarf unwinding on 4.19 kernels:
commit e5adfc3e7e774ba86f7bb725c6eef5f32df8630e
Author: Konstantin Khlebnikov <khlebni...@yandex-team.ru>
Date: Tue Aug 7 12:09:01 2018 +0300
perf map: Synthesize maps only for thread group leader
It looks like this was fixed later by:
commit e8ba2906f6b9054102ad035ac9cafad9d4168589
Author: John Keeping <j...@metanate.com>
Date: Thu Aug 15 11:01:45 2019 +0100
perf unwind: Fix libunwind when tid != pid
but was not selected as a backport to 4.19. Are there plans to backport
the fix? If not, could we have the breaking commit reverted in 4.19 LTS?
Thanks
Josh
