mpi3mr_parent_present(9)

💖 mpi3mr_parent_present — the kernel API manual, bestie edition 💖

okay so this page is from the Kernel API Manual (section 9, the fun one) and it's all about one tiny little question: does this phy even have a parent? 🎀

---

✨ NAME ✨

mpi3mr_parent_present — literally just "is parent present for a phy" 🌸

---

🦋 SYNOPSIS 🦋

int mpi3mr_parent_present (struct mpi3mr_ioc *mrioc , struct sas_phy
*phy );

like, that's the whole function signature, no cap. 🫶

---

💅 ARGUMENTS 💅

• mrioc — your adapter instance reference, the whole vibe check for which HBA we're talking about 👑
• phy — the SAS transport layer phy object, aka the actual little guy we're asking about 🧚

---

⭐ RETURN ⭐

0 if parent is present, else non-zero. that's it, that's the whole answer, fr fr 💀

---

🌈 SEE ALSO 🌈

so many cross-references, we love a well-connected function 💜
