[Mesa-dev] [PATCH v3 00/11] Common pipe screen ref counting

[Rob Herring]

Another version of common pipe_screen reference counting.

Changes in v3:
- dup() fd and store in pipe_screen as the lifetime of the 
pipe_loader_drm_device and pipe_screen are different.
- Fix leaking of pipe_loader_drm_device. Only the last one closed was 
getting freed.
- Move mutex for fd hash table into u_screen.c
