💅 scx_cid_retire_tables(9) — Kernel API Manual ✨

okay so bestie, welcome to the scx_cid_retire_tables(9) page in the Kernel API Manual — this is the cleanup icon we're stanning today. It's giving “unpublish and retire the cid tables,” and honestly? periodt. 💖

🌸 NAME 🌸

scx_cid_retire_tables — Unpublish and retire the cid tables. no cap, that's the whole assignment. 💅

🦋 SYNOPSIS 🦋

void scx_cid_retire_tables (void );

🎀 ARGUMENTS 🎀

• void — no arguments. literally none. it takes nothing, bestie. 🙈

✨ DESCRIPTION ✨

So here's the tea: this one gets called by root disable after the readers that dereference without NULL checks are drained, and it runs inside cpus_read_lock so the hotplug path is excluded. The lock is lowkey the bouncer here — it keeps the hotplug path out of the room. 🫶

🔥 SEE ALSO 🔥
