🎀 NAME 🎀

ror32 — rotate a 32-bit value right 💫

like, you take a 32-bit value and you spin it to the right. that's the whole vibe. 🌀

__u32 ror32 (__u32 word , unsigned int shift );

look at her. three whole tokens and she's done. main character energy fr fr 👑

• word — value to rotate 🌀 this is the thing that's getting spun, okay?
• shift — bits to roll 🎡 how far around the circle we're going, bestie.

🦋 SEE ALSO 🦋

the kernel file for all this is ./include/linux/bitops.h 📁 — that's where the bit-twiddling magic lives, iykyk.

and then there's the whole squad of siblings and cousins, all chillin' in the same orbit 💫: rol64(9), ror64(9), rol32(9), rol16(9), ror16(9), rol8(9), ror8(9), sign_extend32(9), sign_extend64(9), get_count_order_long(9), parity8(9), __ffs64(9), fns(9), assign_bit(9), __ptr_set_bit(9), __ptr_clear_bit(9), __ptr_test_bit(9) 🌈

no cap, that's a whole friend group. go say hi to all of them. 🫶

💀 reminder bestie: rotations are not shifts, and this page is only about the 32-bit rightward one. don't go attributing extra behaviour to her, she's got one job and it's iconic.

and that's the whole page, gorgeous 🌸 this cutie came from ./include/linux, dated October 2026, and she answers to the name ror32(9) — mwah, periodt 💅🎀💖
