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
