✨ SYNOPSIS ✨

cpumask_bits (maskp );

🎀 ARGUMENTS 🎀

• maskp — the struct cpumask *, bestie. That’s the mask we’re pulling bits from 💖

🦋 DESCRIPTION 🦋

Okay so listen: you should only assume nr_cpu_ids bits of this mask are valid. No cap. That’s the vibe check on how many bits you can trust here.

Also real talk — this is a macro, so it’s const-correct. Slay for type safety, honestly 👑
