💅 scx_bpf_put_idle_cpumask — Kernel API Manual, section 9 💅

okay so bestie, welcome to the manual page for scx_bpf_put_idle_cpumask from the Kernel API Manual — section 9, the one and only. This is the part where you release a previously acquired referenced kptr to an idle-tracking cpumask, and honestly? closure is iconic. 💖

✨ NAME ✨

scx_bpf_put_idle_cpumask — release a previously acquired referenced kptr to either the percpu, or SMT idle-tracking cpumask. That’s the whole main-character job, no cap. 💅

🌸 SYNOPSIS 🌸

Here’s the exact signature, bestie — do not retype it with typos:

__bpf_kfunc void scx_bpf_put_idle_cpumask (const struct cpumask
*idle_mask );

🎀 ARGUMENTS 🎀

• idle_mask — the cpumask to use. That’s the argument, that’s the assignment, periodt. 💖
