Sometimes vfio iommu type1 needs to pin memory for a remote task other than current, thereby needs to test the CAP_IPC_LOCK capability for that task.
The proper routine for this purpose is has_capability(), but it is not yet exported for modules. None of currently exported capability- testing symbols allows a specified task. So here has_capability() is exported then used in the vfio iommu type1 driver.
