Hm, maybe a tiny static inline function which canonizalizes modifiers?
Something like
static inline u64
drm_fourcc_canonicalize_nvidia_block_linear_2d(u64 modifer, bool
is_pre_turing)
{
}
Would then give you a nice place to stick this backward compat note and
make it really clear what should be done. I think establishing this as a
pattern would also be nice, since I'm sure we'll have a pile more of these
cases where modifiers turn out to assume a few too many things ab...

[PATCH] drm: Generalized NV Block Linear DRM format mod
Beyond general review, I'm looking for feedback on a few things
specifically here:
-Is the level of backwards compatibility described here sufficient?
Technically I can make the user space drivers support the old
modifiers too, but that would mean the layout they specify would
morph based on the GPU they're being used on, and sharing buffers
between two different NV GPUs, which would
