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 in this series has_capability() is exported then used in the vfio iommu type1 driver.
v2: -> Add Serge's Acked-by to PATCH [1/2] -> Remove the change in vfio_pin_pages_remote, since it's now guaranteed the 'current' process
Hi Alex,
I kept EXPORT_SYMBOL other than EXPORT_SYMBOL_GPL, since I'm still worry about changing the type of existing exports in 'capability.c'. I'm new to open-source fearing of violating GPL :)
