🎀 rcu_barrier_tasks(9) 🎀

okay so bestie, welcome to the Kernel API Manual page for rcu_barrier_tasks — it's short, it's sweet, and it's lowkey iconic. 💖

🌸 NAME 🌸

rcu_barrier_tasks — wait for in-flight call_rcu_tasks() callbacks. Yes, literally wait for those callbacks to finish their little moment. ✨

✨ SYNOPSIS ✨

void rcu_barrier_tasks (void );

that's the whole signature, no cap. 🫶

🫶 ARGUMENTS 🫶

• void — no arguments. Nothing to pass in, bestie. Zero. Nada. The argument list is giving empty and we respect it. 💅

💅 DESCRIPTION 💅

okay so here's the important part: the current implementation is guaranteed to wait, periodt. But it is not obligated to wait — for example, if there are no pending callbacks, it doesn't have to wait, and that's allowed. 🦋
