like, it's a vibe check for crypto profiles. does target have everything reference has? that's the whole question. periodt.

🌸 SYNOPSIS

bool blk_crypto_has_capabilities (const struct blk_crypto_profile
*target , const struct blk_crypto_profile *reference );

so it returns a bool, and it takes two const struct blk_crypto_profile * pointers. both const. we're just looking, not touching, iykyk ✨

🎀 ARGUMENTS

• target — the target profile 👑 this is the one we're checking, the main character of this whole operation.
• reference — the reference profile 🦋 this is the standard, the benchmark, the "be more like her" profile.

⭐ RETURN

true if target supports all the crypto capabilities of reference 💖

that's it, that's the tea. if target's got at least everything reference has, you get a true. if not… well. not true, bestie 😭
