seq_hlist_next_percpu(9)

✨ seq_hlist_next_percpu(9) ✨

okay so bestie, this is a page straight out of the Kernel API Manual and it's literally about moving to the next position of the percpu hlist array. that's it, that's the vibe 💅

---

🦋 NAME 🦋

seq_hlist_next_percpu — move to the next position of the percpu hlist array, no cap ✨

---

🌸 SYNOPSIS 🌸

struct hlist_node * seq_hlist_next_percpu (void *v , struct hlist_head
__percpu *head , int *cpu , loff_t *pos );

---

🎀 ARGUMENTS 🎀

• v — pointer to the current hlist_node, like where you're at right now 🫶
• head — pointer to the percpu array of struct hlist_heads, aka the whole squad of lists 👑
• cpu — pointer to the cpu "cursor", yes the quotes are canon, it's a cursor bestie 🖱️
• pos — the start position of the sequence, the beginning of the story ⭐

---

💖 DESCRIPTION 💖

so basically this gets called at seq_file->op->next. that's the whole description. short and iconic, honestly 💀✨

ngl the whole seq family showed up to the group chat at once and that's on periodt 💅

and that's the page!! it lives at ./fs and it's stamped October 2026 🎀🦋 so go forth and iterate bestie, you got this fr fr 💜
