Hi,

This patch series adds virtual suspend time injection support to KVM.
(It is an updated version of the following series.)
https://lore.kernel.org/kvm/20210426090644.2218834-1-hikalium@chromium.org/

Changes to v1:

- Using IRQ instead of polling to detect the host's suspension.
- Removed unused arg "updated" from kvm_write_suspend_time()
- Improved comments and commit messages.

Please take a look again.

Thanks,

Hikaru Nishida
