Here's a third version of my DRM mode object leases series. Since v2:
* Add revocation. This allows leases to be effectively revoked by
removing all of the objects they have access to. The lease itself
hangs around as it's hanging off a file.
* Allow non-master files to look at all DRM mode objects. This
lets the Vulkan code provide information about the display
environment before the lease is created.
* Free the leases IDR when the master is destroyed. Just a bug fix.
* _drm_lease_held should look at lessees, not lessor. Just a bug fix.
I've also rebased it to a more recent version of Dave's drm-next
branch.
With this and my CRTC-id based vblank series (posted separately), I'm
now running "real" applications on a leased output and can fully
support the following Vulkan extensions:
EXT_direct_mode_display
EXT_acquire_xlib_display
EXT_display_surface_counter
KEITHP_kms_display
