Compiling under kernel 2.6.0 and after
...s you might expect from the file it fails on.
Anyone else had this problem and fixed it?

[RFC PATCH v1 00/34] VM introspection - EPT Views and Virtualization Exceptions
This patch series is based on the VM introspection patches
(https://lore.kernel.org/kvm/20200721210922.7646-1-alazar at bitdefender.com/),
extending the introspection API with EPT Views and Virtualization
Exceptions (#VE) support.
The purpose of this series is to get an initial feedback and to see if
we are on the right track, especially because the changes made to add
the EPT views are not small

[PATCH][RFC][12+2][v3] A expanded CFQ scheduler for cgroups
This patchset expands traditional CFQ scheduler in order to support cgroups,

Improvements are as following.
* Modularizing our new CFQ scheduler.
The expanded CFQ scheduler is registered/unregistered as new I/O
elevator scheduler called "cfq-cgroups". By this, the traditional CFQ

[RFC PATCH v7 00/78] VM introspection
The KVM introspection subsystem provides a facility for applications
running on the host or in a separate VM, to control the execution of
other VMs (pause, resume, shutdown), query the state of the vCPUs (GPRs,
MSRs etc.), alter the page access bits in the shadow page tables (only
for the hardware backed ones, eg. Intel's EPT) and receive notifications
when events of interest have taken place
