epf_ntb_epc...up_interface(9)

💅 epf_ntb_epc_cleanup_interface — a Kernel API Manual moment 🎀

okay so bestie, welcome to the Kernel API Manual, we're talking about epf_ntb_epc_cleanup_interface(9) today and honestly? she's a little cleanup queen and we stan. ✨

---

🌸 NAME 🌸

epf_ntb_epc_cleanup_interface — literally just Cleanup NTB interface. that's the whole vibe. no cap. 🧹💖

---

🦋 SYNOPSIS 🦋

void epf_ntb_epc_cleanup_interface (struct epf_ntb *ntb , enum
pci_epc_interface_type type );

like, she returns void (no tea, no shade, no return value) and she takes exactly two things. that's it. 🫶

---

💜 ARGUMENTS 💜

• ntb — the NTB device that facilitates communication between HOST1</> and HOST2</>. she's the middleman, the connector, the group-chat admin keeping both hosts talking. 💬👑
• type — either the PRIMARY</> interface or the SECONDARY</> interface. pick your fighter, bestie, but only one of these two. 🎀

---

⭐ DESCRIPTION ⭐

so here's the tea: this function is a wrapper to cleanup a particular NTB interface. that's the whole job. she wraps, she cleans up, she leaves. iconic behaviour honestly, lowkey the most relatable function in the file. 💅✨

no extra steps, no secret side quests — wrapper, particular NTB interface, cleanup. periodt. 🧚
