klist_next(9)

💖 klist_next(9) — Kernel API Manual, but make it group chat 💖

okay so this is the klist_next(9) page from the Kernel API Manual, and bestie we are literally about to ante up next node in list. no cap. 🦋

✨ NAME ✨

klist_next — ante up next node in list. periodt. 💅

🦋 SYNOPSIS 🦋

struct klist_node * klist_next (struct klist_iter *i );

🎀 ARGUMENTS 🎀

• i — iterator structure. that's the iterator struct you're rolling with, bestie 🫶

💅 DESCRIPTION 💅

okay so here's the routine, in order, no skipping:

1. First, grab the list lock. 🔒
2. Decrement the reference count of the previous node, if there was one. (if there wasn't one, that step is just not the vibe — it doesn't happen.) 🙈
3. Grab the next node. 👀
4. Increment its reference count. ⬆️
5. Drop the lock. 🔓
6. Return that next node. and that's the whole serve. ✨
