💅 batadv_neigh_node_release(9) — the Kernel API Manual glow-up

okay so bestie, welcome to batadv_neigh_node_release — a little function in the Kernel API Manual and honestly? she's doing the cleanup work nobody claps for. 🧹✨

✨ NAME ✨

batadv_neigh_node_release — release neigh_node from lists and queue for free after rcu grace period

like, she unlinks the neigh_node from her lists and then queues her up to be freed after the RCU grace period, because you can't just yank a girl out of memory while readers might still be looking at her. 😭 rcu grace period is giving waiting-for-the-group-chat-to-go-quiet before you delete the messages. fr fr.

bestie reminder: the freeing is deferred — queued for free after the rcu grace period, not instant. don't go touching her after you call this. 🙈
