🦋 list_splice_init_rcu(9) 🦋

okay so welcome to the Kernel API Manual corner of the group chat, bestie. Today’s main character is list_splice_init_rcu, and she is here to do exactly one splice-related thing. no cap. 💅

🌸 NAME 🌸

list_splice_init_rcu — splice an RCU-protected list into an existing list, designed for stacks. that’s the whole assignment, and she ate. ✨

✨ SYNOPSIS ✨

void list_splice_init_rcu (struct list_head *list , struct list_head
       *head , void (*sync)(void) );

🎀 ARGUMENTS 🎀

• list — the RCU-protected list to splice. that’s the list on deck.
• head — the place in the existing list to splice the first list into. lowkey the destination vibe.
• sync — the sync hook is synchronize_rcu, synchronize_rcu_expedited, ... — yes, the ... is doing its little mysterious thing. iykyk.
