vdo_unassig...al_reference(9)

okay bestie, you opened vdo_unassig...al_reference(9) from the Kernel API Manual, and this page is short but lowkey important. Let's get into it 💅

💖 NAME 💖

vdo_unassign_pbn_lock_provisional_reference — informs a PBN lock that it is no longer responsible for a provisional reference. That's the whole vibe: one lock, one provisional-reference notice, no extra plot. It's giving tiny-but-iconic kernel helper, fr fr. 🫶

✨ SYNOPSIS ✨

copy this exactly, bestie — no renaming, no improv:

void vdo_unassign_pbn_lock_provisional_reference (struct pbn_lock *lock
       );

🎀 ARGUMENTS 🎀

• lock — the PBN lock. One argument, main character energy, that's it. 🎀
