destroy_rcu_head_on_stack(9)

🌸 NAME 🌸

bestie, this is the Kernel API Manual page for destroy_rcu_head_on_stack(9) 💅 — destroy_rcu_head_on_stack = destroy on-stack rcu_head for debugobjects. That's the NAME tea, periodt ✨

✨ SYNOPSIS ✨

void destroy_rcu_head_on_stack (struct rcu_head *head );

🎀 ARGUMENTS 🎀

• head — pointer to rcu_head structure to be initialized. Yes, “initialized” — we’re not changing the original wording, bestie 🫶

💖 DESCRIPTION 💖

okay so this function informs debugobjects that an on-stack rcu_head structure is about to go out of scope. 💅 As with init_rcu_head_on_stack, this function is not required for rcu_head structures that are statically defined or that are dynamically allocated on the heap. Also as with init_rcu_head_on_stack, this function has no effect for !CONFIG_DEBUG_OBJECTS_RCU_HEAD kernel builds. No cap, that's the whole vibe ☕✨
