[PATCH 0/2] drm: update the ioctl handler
From: Desmond Cheong Zhi Xi

Hi,
Finally got around to it. This patchset implements some updates to the
drm ioctl handler that were first raised by Daniel Vetter in [1].
Namely:
- Flush concurrent processes that can change the modeset when
DRM masters are set/dropped or a lease is revoked
- Unexport drm_ioctl_permit()
Thoughts and comments would be very appreciated.

Best wishes,
