free_pbn_lock_pool(9)

💅 free_pbn_lock_pool(9) 💅 Kernel API Manual

🌸 NAME 🌸

free_pbn_lock_pool — free a PBN lock pool. That’s the whole name, periodt. 💖

✨ SYNOPSIS ✨

void free_pbn_lock_pool (struct pbn_lock_pool *pool );

🎀 ARGUMENTS 🎀

• pool — the lock pool to free. That’s the one and only arg, bestie. 🫶

🦋 DESCRIPTION 🦋

Okay so listen: this function frees a PBN lock pool. But it doesn’t just free the pool itself — it also frees all the PBN locks it allocated, no cap. 😭

Because of that, the caller must ensure that all locks have been returned to the pool before calling this. Like, every single lock needs to be back home first. No stragglers, no “oops I forgot one” energy. 💀
