Re: [PATCH v7 01/12] PCI: liveupdate: Set up FLB handler for the PCI core

[sashiko-bot@kernel.org]

> Set up a File-Lifecycle-Bound (FLB) handler for the PCI core to enable
> it to participate in the preservation of PCI devices across Live Update.
> Essentially, this commit enables the PCI core to allocate a struct
> (struct pci_ser) and preserve it across a Live Update whenever at least
> one device is preserved.
> 
> Preserving PCI devices across Live Update is built on top of the Live
> Update Orchestrator's (LUO) support for file preservation. Drivers are
> expected to expose a file to userspace to represent a single PCI device
> and support preservation of that file. This is intended primarily to
> support preservation of PCI devices bound to VFIO drivers.
> 
> This commit enables drivers to register their liveupdate_file_handler
> with the PCI core so that the PCI core can do its own tracking and
> enforcement of which devices are preserved.
