Thanks, but why specifically this header? The other exynos/*.h headers
also lack the c++ mangling guard.

A quick grep shows that only 15/101 headers in libdrm have it.
Can I interest you in fixing a few more headers? :)

In any case, this patch is:
Reviewed-by: Eric Engestrom <eric.engestrom@imgtec.com>
(I assume you'll push it yourself?)

Btw, can you run this in your local libdrm repo?
  $ git config --local format.subjectPrefix "PATCH libdrm"

Cheers,
  Eric

I'm currently writing a small C++ project using the
exynos_bo_{create,destroy}() calls, and noticed this.

Not at the moment.

FTR, only the installed headers (~50) need the extern C guard.
None of that is not a blocker for this patch, so I've just pushed it to master.

Thanks!

Thanks Emil. I'll see what I can do about the other ones.
