I think you can just rename flags->info and offset->value, the rest of
the struct should be zero-initialized.. if in doubt you can check
$mesa/src/freedreno/drm/msm_bo.c
side-note: the libdrm_freedreno code was folded into mesa in 19.0, so
at *some* point we can probably disable libdrm_freedreno build by
default. (I'd kinda still like to keep the code around for some misc
standalone tools I have, but that is the sort of thing where I can fix
libdrm if it gets broken). When to switch to disabled by default I
guess comes down to how long we want to support mesa 18.x with latest
libdrm?? Maybe after 19.1, since (selfishly motivated) that gives me
a long enough window back in case I find myself needing to bisect for
some regression..
