Subject: [PATCH 0/2] test capability for remote task

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.

Jike Song (2):
  capability: export has_capability
  vfio iommu type1: fix the testing of capability for remote task
