However Rob Clark pointed out that, rather than keep one of the tricks I had used, it would be better to change the helpers resulting in this series. I've tested this both with a rather hacked about Android userspace and with a fairly small test case run from debian. Both bits of code currently use dumb buffers. Thanks to Benjamin Gaignard for his help in finding this bit of code and to Damien Hobson-Garcia for pointing out that I'd forgotten (since 3.18) to RESEND these patches. Dave: I guess its probably too late in the dev. cycle to take this code but don't worry, I will try really hard to remember to RESEND it for 4.2. ;-) v2: * Modified DRM_PRIME_HANDLE_TO_FD to honour the O_RDRW from the user and removed code to workaround this from the sti driver (Rob Clark). * Added a patch to (rather spartanly) document gem_prime_mmap. Only tacked into this series 'cos I spotted it was missing when I was checking whether I needed to describe DRM_RDRW anywhere.
