xas_next_entry(9)

💅 xas_next_entry — Kernel API Manual realness

okay so welcome to xas_next_entry(9), straight out of the Kernel API Manual, and bestie… it's a tiny little inline function that just moves the iterator forward. That's it. That's the whole vibe. ✨

---

🌸 NAME 🌸

xas_next_entry — advance that iterator to the next present entry. slay.

---

🎀 SYNOPSIS 🎀

void * xas_next_entry (struct xa_state *xas , unsigned long max );

---

🦋 ARGUMENTS 🦋

• xas — the XArray operation state. the main character of this whole situation, lowkey.
• max — the highest index it's allowed to return. like, the ceiling. respectfully.

---

💖 DESCRIPTION 💖

so xas_next_entry is an inline function whose whole personality is optimising xarray traversal for speed. it's giving "I'm the fast path" energy fr fr.

it is equivalent to calling xas_find, and — important — it will call xas_find for all the hard cases. so like, it handles the easy stuff itself and outsources the messy drama. iconic delegation tbh.

---

✨ RETURN ✨

the next present entry after the one currently referred to by xas. that's the tea. 🫶
