lower_48_bits(9)

💅 lower_48_bits(9)

okay bestie, welcome to the Kernel API Manual — yes we're doing kernel API now, we contain multitudes 💖

✨ NAME ✨

lower_48_bits — literally just returns bits 0-47 of a number. that's it. that's the whole vibe. a little slice of your u64, freshly cut 🎀

🌸 SYNOPSIS 🌸

u64 lower_48_bits (u64 n );

🦋 ARGUMENTS 🦋

• n — the number we're accessing. hand it over and it gives you back the bottom 48 bits, no cap 🫶

👑 SEE ALSO 👑

• Kernel file ./include/linux/t10-pi.h — go look, it's giving source material ✨

lowkey a tiny function but it ate and left no crumbs. just remember: 48 bits in, 48 bits out 🔥

and that's the whole page, bestie — no notes, iconic behavior 💅

mwah 💜 this little gem lives in ./include/linux and the version of record is dated October 2026 — see you then, xoxo 🎀✨
