nvmet_fc_reg...r_targetport(9)

👑 NAME 👑

nvmet_fc_register_targetport — the transport entry point that an LLDD calls to register that a local NVME subsystem FC port exists 💅 this is the "hey bestie, I'm here, I'm a port, pls acknowledge me" moment, and it lives in the Kernel API Manual 🎀

✨ SYNOPSIS ✨

int nvmet_fc_register_targetport (struct nvmet_fc_port_info *pinfo ,
struct nvmet_fc_target_template *template , struct device *dev , struct
nvmet_fc_target_port **portptr );

🦋 ARGUMENTS 🦋

• pinfo — pointer to info about the port you're registering. literally the port's little ID card 🪪
• template — the LLDD entrypoints and the operational parameters for the port. this is where you hand over all the callbacks, no cap 🔥
• dev — the physical hardware device node that this port corresponds to. it's gonna be used for DMA mappings, so like… it matters, okay? 💖
• portptr — pointer to a local port pointer 👀 here's the tea: on success, the routine allocates a nvme_fc_local_port structure and drops its address into the local port pointer. on failure, that local port pointer gets set to NULL 🫶

🌸 RETURN 🌸

a completion status, bestie 📋 it must be 0 on success, and a negative errno (ex: -ENXIO) on failure. zero = slay, negative = the vibe check failed 😭
