release_data...ocation_lock(9)

💅 release_data_vio_allocation_lock — the Kernel API Manual moment 🎀

okay so bestie, we're in the Kernel API Manual today and this page is literally called release_data...ocation_lock(9) (the header up top is just being dramatic and truncating itself, it's fine, we stan a mysterious queen). let's get into it ✨

---

🌸 NAME 🌸

release_data_vio_allocation_lock — releases the PBN lock on a data_vio's allocated block. that's the whole vibe. no notes. 💖

---

✨ SYNOPSIS ✨

void release_data_vio_allocation_lock (struct data_vio *data_vio , bool reset );

look at her. succinct. iconic. 🫶

---

🎀 ARGUMENTS 🎀

• data_vio — the data_vio. that's it, that's the description, she's serving minimalism 💅
• reset — if it's true, the allocation gets reset — meaning any allocated pbn will be forgotten. gone. deleted. not me crying over a pbn 😭

---

🦋 DESCRIPTION 🦋

so here's the tea: if the reference to the locked block is still provisional, it gets released as well. like, it's not locked in yet, so it also gets let go. both of them. together. slay 🔥
