_transport_phy_reset(9)

✨ _transport_phy_reset(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 you're literally about to read the page for _transport_phy_reset(9), and honestly it's giving "short and mysterious." We love a lowkey icon. 🎀

---

🌸 NAME 🌸

_transport_phy_reset —

no cap, the original page leaves the description completely blank after that dash 😭 like the author said "the name speaks for itself" and clocked out. So we're just gonna sit here together in the silence. 🫶

---

✨ SYNOPSIS ✨

int _transport_phy_reset (struct sas_phy *phy , int hard_reset );

that's it. that's the whole function signature. it takes two things and gives you back an int, and we're gonna talk about all of those things right now 👑

---

🦋 ARGUMENTS 🦋

• phy — the sas phy object 💅 this is the thing you're handing over. it's a struct sas_phy *, it's the main character, it's the whole reason we're here.
• hard_reset — okay so bestie, the original page does not tell us what this one does. it's just sitting there. empty. an int with no description, a vibe with no lore 🙈 not me refreshing the manpage hoping more text appears. it doesn't. we move.

---

🔥 RETURN 🔥

• 0 — success, we ate, everything's slaying ✅
• non-zero — failure, it's giving struggle 😭

fr fr: if you get anything other than 0 back, that's your signal that it did not work. don't ignore it, babe.
