From: Tianyu Lan <Tianyu.Lan@microsoft.com>
This patchset fixes some issues in the Hyper-V panic code path. Patch 1 resolves issue that panic system still responses network packets. Patch 2-3,5-6 resolves crash enlightenment issues. Patch 4 is to set crash_kexec_post_notifiers to true for Hyper-V VM in order to report crash data or kmsg to host before running kdump kernel.
Tianyu Lan (6): x86/Hyper-V: Unload vmbus channel in hv panic callback x86/Hyper-V: Free hv_panic_page when fail to register kmsg dump x86/Hyper-V: Trigger crash enlightenment only once during 0;136;0c0;136;0c system crash. x86/Hyper-V: Report crash register data or kmsg before running crash kernel x86/Hyper-V: Report crash register data when sysctl_record_panic_msg is not set x86/Hyper-V: Report crash data in die() when panic_on_oops is set
