Welcome to this Kernel API Manual page, bestie. We're talking about the function that un-initializes resources associated with the zbus and free memory. It's giving cleanup era. 💅

💖 NAME 💖

zpci_bus_release — Un-initialize resources associated with the zbus and free memory.

✨ SYNOPSIS ✨

void zpci_bus_release (struct kref *kref );

No cap, that's the whole signature. ✨

🎀 ARGUMENTS 🎀

• kref — this is a refcount * that's part of struct zpci_bus. That's the little refcount bestie it needs. 🫶

🦋 DESCRIPTION 🦋

Okay so listen: this one MUST be called with zbus_list_lock held. But here's the plot twist — the lock is released during run of the function. So yeah, you come in holding the lock, and the function lets it go while it's doing its thing. Not me being dramatic, that's literally the description. 💀
