💅 phy_package_leave(9)

okay so this is a page from the Kernel API Manual, and the function we're stanning today is phy_package_leave — she's the one who leaves the group chat. no cap.

---

✨ NAME ✨

phy_package_leave — leave a common PHY group 🫶

---

🌸 SYNOPSIS 🌸

void phy_package_leave (struct phy_device *phydev );

---

🎀 ARGUMENTS 🎀

• phydev — the target phy_device struct. bestie, this is the PHY you're pulling out of the group 💫

---

🦋 DESCRIPTION 🦋

so here's the vibe: this function leaves a PHY group — specifically one that was created by phy_package_join. like, you joined the server, now you're dipping 👋

and here's the part that's lowkey important: if this phydev happened to be the last user of the shared data between the group, then that data gets freed. last one out turns off the lights, fr fr. 💀

it also resets the phydev->shared pointer to NULL. clean break. no leftover read receipts. ✨
