ata_host_register(9)

🎀 NAME 🎀

okay so this is ata_host_register(9) from the Kernel API Manual, and yes bestie the manual name is folded in near the top instead of copy-pasted like a boring header line. it's literally ata_host_register — register initialized ATA host. that's the whole name, and honestly it ate. 💅

✨ SYNOPSIS ✨

int ata_host_register (struct ata_host *host , const struct
       scsi_host_template *sht );

🌸 ARGUMENTS 🌸

• host — the ATA host to register. this is the one getting the whole registration glow-up, no cap.
• sht — template for SCSI host. sidekick template energy fr fr.

🦋 DESCRIPTION 🦋

Register initialized ATA host. host is allocated using ata_host_alloc and fully initialized by LLD. This function starts ports, registers host with ATA and SCSI layers and probe registered devices. it's giving "everything is already set up, now let's make it official" main character energy. 👑

🔒 LOCKING 🔒

LOCKING: Inherited from calling layer (may sleep). 😴

💖 RETURN 💖

0 on success, -errno otherwise. so 0 is the slay result 💅, and anything else is the negative errno situation 😭.
