The patches are also partly in focal:
fb5c915cdd37 "PCI/IOV: Mark VFs as not implementing PCI_COMMAND_MEMORY"
23af8153d85e "vfio/pci: Decouple PCI_COMMAND_MEMORY bit checks from is_virtfn"
They came in 'Focal update: v5.4.73 upstream stable release' LP 1902115.
However, 08b6e22b850c "vfio/pci: Decouple PCI_COMMAND_MEMORY bit checks from
is_virtfn" is missing.
I checked all other upstream stable bugs for focal, this one is not addressed.
Hence this ticket boils down to cherry picking 08b6e22b850c "s390/pci:
Mark all VFs as not implementing PCI_COMMAND_MEMORY" into focal master-
next.
** Changed in: linux (Ubuntu Focal)
Status: New => In Progress
