put_unbound_pool(9)

🌸 NAME 🌸

put_unbound_pool — put a worker_pool 💅 and yes bestie, this page is serving Kernel API Manual energy, iykyk 🫶

✨ SYNOPSIS ✨

void put_unbound_pool (struct worker_pool *pool );

🎀 ARGUMENTS 🎀

• pool — the worker_pool you're putting, bestie.

💖 DESCRIPTION 💖

Okay so: put pool. If its refcnt reaches zero, it gets destroyed in an RCU safe manner — periodt 💀✨. get_unbound_pool calls this function on its failure path, and this function should be able to release pools which went through, successfully or not, init_worker_pool. It's giving cleanup-that-handles-everything energy, fr fr 🧚

Vibe check: this should be called with wq_pool_mutex held 🔒😭.
