SubjectRE: [PATCH V3 4/6] x86/Hyper-V: Report crash register data or ksmg before running crash kernel
Date
From: Tianyu Lan <Tianyu.Lan@microsoft.com> Sent: Tuesday, March 24, 2020 12:57 AM

> We want to notify Hyper-V when a Linux guest VM crash occurs, so
> there is a record of the crash even when kdump is enabled. But
> crash_kexec_post_notifiers defaults to "false", so the kdump kernel
> runs before the notifiers and Hyper-V never gets notified. Fix this by
> always setting crash_kexec_post_notifiers to be true for Hyper-V VMs.
