I guess this race doesn't really matter as if you try to use the file before finit() you just get badfileops and finit() itself is "atomic"? If so, I could just leave this as-is unless this approach is preferred.

No objection, but I believe you're correct about finit() being "atomic." (I mean, it is atomic. But are the fops consumers?)

sys/opencrypto/cryptodev.c
1516	Will the compiler complain about storing `fd` to a `uint32_t` lvalue? I guess that part has not changed, so no.
