Subject: [PATCH 0/2] test capability for remote task
Date: Thu, 22 Dec 2016 00:10:14 +0800 [thread overview]
Message-ID: <1482336616-19252-1-git-send-email-jike.song@intel.com> (raw)
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
