💅 cipso_v4_doi_search — it's in the kernel API manual (section 9), bestie 🎀

Okay so picture this: you're deep in cipso_v4_doi_search(9) and you just need to find one specific DOI definition. That's literally the whole vibe. Let's go ✨

✨ NAME ✨

cipso_v4_doi_search — searches for a DOI definition 🔍💖

🌸 SYNOPSIS 🌸

struct cipso_v4_doi * cipso_v4_doi_search (u32 doi );

🦋 ARGUMENTS 🦋

  • doi — the DOI you're searching for, bestie. That's it, that's the argument 🫶

💜 DESCRIPTION 💜

So what this does: it searches the DOI definition list for a DOI definition whose DOI value matches doi. Simple, iconic, does exactly what it says on the tin 👑

Now the part you cannot skip, no cap: the caller is responsible for calling rcu_read_[un]lock. That's on you, not on this function. Don't come for me, come for your own locking discipline 😭🔒

It returns a pointer to the DOI definition on success, and NULL on failure. Slay 🎀
