stable inclusion from stable-v5.10.154 commit e5d7c6786befe4aca0ba645dc5b836fc60ea733c category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I64YCB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e5d7c6786befe4aca0ba645dc5b836fc60ea733c -------------------------------- [ Upstream commit a61d7c54 ] Trace exceptions that are re-injected, not just those that KVM is injecting for the first time. Debugging re-injection bugs is painful enough as is, not having visibility into what KVM is doing only makes things worse. Delay propagating pending=>injected in the non-reinjection path so that the tracing can properly identify reinjected exceptions.
