Alex Williamson 890ed578df vfio-pci: Use pci "try" reset interface ... PCI resets will attempt to take the device_lock for any device to be reset. This is a problem if that lock is already held, for instance in the device remove path. It's not sufficient to simply kill the user process or skip the reset if called after .remove as a race could result in the same deadlock. Instead, we handle all resets as "best effort" using the PCI "try" reset interfaces. This prevents the user from being able to induce a deadlock by triggering a reset.
