lpfc_unregister_unused_fcf(9)

✨ lpfc_unregister_unused_fcf(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this little cutie lives in lpfc_unregister_unused_fcf(9) and honestly? it's giving cleanup era.

---

🌸 NAME 🌸

lpfc_unregister_unused_fcf — unregister that FCF when literally every device is disconnected 🫶

🦋 SYNOPSIS 🦋

void lpfc_unregister_unused_fcf (struct lpfc_hba *phba );

like, that's the whole vibe. void, no return, no notes 💅

🎀 ARGUMENTS 🎀

• phba — pointer to the hba context object. yes queen, we need the context 👑

⭐ DESCRIPTION ⭐

so what this function actually does: it checks if there are any connected remote port for the FCF, and if all the devices are disconnected, this function unregisters the FCFI. iconic behavior, no cap ✨

it also tries to use another FCF for discovery — because we're not just gonna leave discovery hanging, that would be so rude 😭

ngl this is the "check the group chat, and if everyone's gone, dip" energy. but for remote ports. and FCFs. 🧚
