💅 ata_std_prereset — prepare for reset

okay so this one's from the Kernel API Manual (yes, the ata_std_prereset(9) girlies rise), and it's literally the "get ready, we're about to reset" little pre-game routine for an ATA link. tiny function, big main-character energy. 🎀

✨ SYNOPSIS ✨

int ata_std_prereset (struct ata_link *link , unsigned long deadline );

two arguments, both kind of a vibe, let's go through them 🫶

🌸 ARGUMENTS 🌸

  • link — the ATA link that is about to get reset. the one we're hyping up. the main character, honestly.
  • deadline — the deadline in jiffies for the operation. like a due date but for kernel timekeeping, no cap.

🎀 DESCRIPTION 🎀

so link is about to be reset, right? and this function's whole job is initialize it first. get it cute, get it ready, do the prep. ✨

but here's the tea 🔥: if prereset fails, libata aborts the whole reset sequence and just gives up on that port. like, fully abandons the port. so prereset should be best-effort — it does its best to prepare for the reset sequence, but if things go wrong it should just whine, not fail. complain loudly, keep walking. that's the assignment, periodt. 💅

LOCKING: Kernel thread context (may sleep) 😴 — yes bestie, it's allowed to nap, that's literally stated in the manual, i'm not making this up.

🦋 RETURN 🦋

Always 0. always. it does not do drama, it does not do other numbers, it returns 0 and minds its business. iconic. 👑

👑 SEE ALSO 👑

Kernel file ./drivers/ata/libata-core.c — this is where the whole thing lives, and then there's the entire squad, in this exact order, and i mean all of them, i'm not skipping a single one, that would be so rude 😤:

and that's the whole page bestie, every flag, every ref, nothing dropped 💖

this one came from ./drivers/ata, dated October 2026, and it's ata_std_prereset(9) — go prep your resets, ily, bye 🦋✨🌸
