RH-Commit: [4/67] 8287f687ef19cd84afede1e8f3b16ac3caf29a1d (eauger1/centos-qemu-kvm)
|
||
|
|
|
||
|
|
This adds two helper functions vfio_container_init/destroy which will be
|
||
|
|
used by both legacy and iommufd containers to do base container specific
|
||
|
|
initialization and release.
|
||
|
|
|
||
|
|
No functional change intended.
