alloc_fcdev(9)

💅 alloc_fcdev(9) — like, the Kernel API Manual, bestie ✨

okay so real talk, this is alloc_fcdev from the kernel API manual — the fibre channel device registration girlie. she's giving very specific, very niche, very iconic. let's get into it 🎀

---

🌸 NAME 🌸

alloc_fcdev — Register fibre channel device

like, that's her whole job. registering a fibre channel device. no cap. 💖

---

✨ SYNOPSIS ✨

struct net_device * alloc_fcdev (int sizeof_priv );

that's the whole signature, bestie — she returns a struct net_device * and takes exactly one int called sizeof_priv. periodt. 🫶

---

🦋 ARGUMENTS 🦋

• sizeof_priv — the size of the extra driver-private structure that gets allocated for this fibre channel device. so like, however much extra room your driver needs to keep its own lil stuff in there? that's the number you hand her. 💜

---

🔥 DESCRIPTION 🔥

so what she does is fill in the fields of the device structure with fibre channel-generic values. very "here's the defaults, you're welcome" of her. 💅

she constructs a brand new net device, and it comes complete with a private data area of size sizeof_priv. yup, she's building the whole thing for you. main character energy fr fr. 👑

and the detail that matters: a 32-byte (not bit!) alignment is enforced for this private data area. not bit, bestie — byte. she said don't even think about mixing those up. 😭

🌈 SEE ALSO 🌈

• Kernel file ./net/802/fc.c — go read her, iykyk 📖

and that's the whole page! source is ./net/802, dated October 2026 — so like, mark your calendar, she's from the future 💀✨ mwah, love u, go register some fibre channel devices 🧚‍♀️💖
