bpf_cpumask_equal(9)

🎀 bpf_cpumask_equal(9) — Kernel API Manual 🎀

okay bestie, welcome to the bpf_cpumask_equal(9) page — it's short, it's sweet, and it's literally just checking if two cpumasks are twinning. 💅

🌸 NAME

bpf_cpumask_equal — check two cpumasks for equality. It's giving “are we the same, or are we different?” main character energy. ✨

🦋 SYNOPSIS

__bpf_kfunc bool bpf_cpumask_equal (const struct cpumask *src1 , const
       struct cpumask *src2 );

🎀 ARGUMENTS

• src1 — the first input. Your first little cpumask bestie. 💖
• src2 — the second input. The other one being compared. 🫶

✨ RETURN

• true — src1 and src2 have the same bits set. slay, they match. ✅
• false — src1 and src2 differ in at least one bit. not me spotting a difference. ❌

💜 DESCRIPTION

okay so the lore is simple: struct bpf_cpumask pointers may be safely passed to src1 and src2. no cap, that's the whole vibe check. 🧚
