Subject: [PATCH 0/7] Enhance the hv_vmbus driver to support hibernation
Date: Tue, 9 Jul 2019 05:29:24 +0000	[thread overview]
Message-ID: <1562650084-99874-1-git-send-email-decui@microsoft.com> (raw)

Hi,
This is the first patchset to enable hibernation when Linux VM runs on Hyper-V.

A second patchset to enhance the high-level VSC drivers (hv_netvsc,
hv_storvsc, etc.) for hibernation will be posted later. The second patchset
depends on this first patchset, so I hope this pathset can be accepted soon.

The changes in this patchset are mostly straightforward new code that only
runs when the VM enters hibernation, so IMHO it's pretty safe to have this
patchset, because the hibernation feature never worked for Linux VM running
on Hyper-V.

The patchset is rebased on Linus's tree today.

Please review.

Thanks,
Dexuan
