__cacheline..._end_aligned(9)

💅 __cacheline..._end_aligned — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual, and today's main character is __cacheline_group_end_aligned. she's the closing bracket of the cacheline group world, and honestly? iconic. 🎀

---

🌸 NAME 🌸

__cacheline_group_end_aligned — declare an aligned group end. that's it, that's the vibe. she ends things, and she ends them aligned. periodt. 💅

---

✨ SYNOPSIS ✨

__cacheline_group_end_aligned (GROUP , ... );

---

🦋 ARGUMENTS 🦋

• GROUP — name of the group. literally just the group's name, bestie, nothing deeper than that 💖
• ... — optional alignment. and no, you don't get to invent a new one: it's the same as was in __cacheline_group_begin_aligned, so keep it matching or the vibes will be off 🙈

---

💜 DESCRIPTION 💜

okay so here's the tea 🍓 and it's important:

note that the end marker is aligned to sizeof(long) — that's so you can do a more precise size assertion. yes, precision! we love her! ✨

she also declares a padding at the end, and the whole reason is to avoid the next field falling into this cacheline. like, no cap, that's the entire point — nobody's field is crashing this cacheline's party. 🚫🫶

and that's the whole page, bestie! 🌈 this one came out of ./include/linux and the manual's stamped October 2026, so jot that down, mwah 💋👑
