ata_finalize_port_ops(9)

💅 ata_finalize_port_ops(9) — Kernel API Manual, but make it group-chat 💅

okay so bestie, this is the Kernel API Manual page for ata_finalize_port_ops(9), and we are about to finalize some ata_port_operations together. main character kernel energy only 💖

🌸 NAME 🌸

ata_finalize_port_ops — finalize ata_port_operations, periodt.

✨ SYNOPSIS ✨

void ata_finalize_port_ops (struct ata_port_operations *ops );

🎀 ARGUMENTS 🎀

• ops — the ata_port_operations you're finalizing, bestie.

🦋 DESCRIPTION 🦋

Okay so picture this: an ata_port_operations can inherit from another ops, and that ops can also inherit from another ops. This can go on as many times as necessary, as long as there's no loop in the inheritance chain — no circular drama, no cap.

Ops tables are finalized when the host is started. Any NULL or unspecified entries are inherited from the “closet ancestor” which has the method, and then the entry is populated with it. After finalization, the ops table directly points to all the methods, and ->inherits is no longer necessary and gets cleared. iconic cleanup behavior 💅

Using ATA_OP_NULL, inheriting ops can force a method to NULL. lowkey powerful.

LOCKING: None.
