Currently DRM_IOCTL_PRIME_HANDLE_TO_FD rejects all flags except
(DRM|O)_CLOEXEC making it hard for the userspace to generate a file

It is easy to relax the restriction and allow read/write permissions.
This should be safe because the flags are seldom touched by drm; mostly
they are passed verbatim to dma_buf calls.

It's a little bit old by now, but I'm wondering if someone call tell me
whether this patch is likely to be merged sometime, or has it been
(should it be?) abandoned.
For me, this code remains useful and it would be good to merge it.
I accidentally removed the whole patchset from my
"keep-resending-these-patches" when patch 3 went upstream... I'll rebase
this when I get a chance.
Daniel.
PS
Damn it all..., Rob may (or may not) remember my saying I had trouble
getting the DRM GFX code to come up on my Android/IFC6410 port. Losing
track of this patch would certainly explain it!
