[PATCH 1/9] drm/vblank: Add vblank works

[Sam Ravnborg]

Hi Tejun

You were not the only one who liked it :-)

We ended up with an updated explanation in drm_vblank.c:
https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_vblank.c

Including some nice ascii art in the final version.

It will hit upstream in next merge window.
