Most of my thinking/motivation for this is in the patch notes. The change itself is straightforward, we would like to have some record of when a device is bound or unbound in order to trace back to the time when it happened. Example from dmesg on 6.6.1 kernel: [ 9.935877] vfio-pci 0000:63:00.0: binding to vfio control [ 9.936890] vfio-pci 0000:e1:00.0: binding to vfio control [ 9.937616] vfio-pci 0000:63:00.1: binding to vfio control [ 9.938201] vfio-pci 0000:e1:00.1: binding to vfio control Matthew W Carlis (1): vfio/pci: Log/indicate devices being bound & unbound. drivers/vfio/pci/vfio_pci_core.c | 4 ++++ 1 file changed, 4 insertions(+) base-commit: ceb6a6f023fd3e8b07761ed900352ef574010bcb -- 2.17.1
