list_splice_rcu(9)

💖 list_splice_rcu(9) 💖

okay so bestie, welcome to the Kernel API Manual page for list_splice_rcu(9) — we’re folding that title right into the intro because it’s the main character today 🎀✨

🌸 NAME 🌸

list_splice_rcu — splice a non-RCU list into an RCU-protected list, designed for stacks. it’s giving stack-splice realness, and we’re obsessed 💅

🦋 SYNOPSIS 🦋

void list_splice_rcu (struct list_head *list , struct list_head *head );

🎀 ARGUMENTS 🎀

• list — the non RCU-protected list to splice 🫶
• head — the place in the existing RCU-protected list to splice 🌈

💜 DESCRIPTION 💜

The list pointed to by head can be RCU-read traversed concurrently with this function. ngl that’s the whole vibe: this function is doing its splice thing while the head list can be RCU-read traversed at the same time 👑 no cap, that’s the concurrency moment.
