acpi_bus_trim(9)

🎀 NAME 🎀

okay so bestie, welcome to acpi_bus_trim(9) from the Kernel API Manual 💖 this function’s whole thing is to detach scan handlers and drivers from ACPI device objects — that’s the name, that’s the game, no cap ✨

void acpi_bus_trim (struct acpi_device *adev );

🦋 ARGUMENTS 🦋

• adev — the root of the ACPI namespace scope to walk. that’s your starting point, bestie 🚶‍♀️

💅 DESCRIPTION 💅

okay so the one rule that is literally non-negotiable: this must be called under acpi_scan_lock. not “maybe”, not “if the vibes are right” — must. consider it the function’s main-character requirement 🔒👑
