clear_va_list_locked(9)

✨ clear_va_list_locked — free virtual addresses list ✨

okay bestie, welcome to the clear_va_list_locked page 💅 this is a section 9 kernel API manual page (yes, the Kernel API Manual, we're in the big leagues now 🎀), and it's genuinely so straightforward you're gonna wonder why you were nervous.

---

🦋 NAME 🦋

clear_va_list_locked — literally just frees a virtual addresses list. that's the whole vibe. ngl it does what it says on the tin 💖

---

🌸 SYNOPSIS 🌸

void clear_va_list_locked (struct hl_device *hdev , struct list_head
*va_list );

returns void, so no "did it work??" anxiety, she just does it and leaves ✨

---

🎀 ARGUMENTS 🎀

• hdev — the habanalabs device structure. the main character device struct 🫶
• va_list — list of virtual addresses to free. this is the list she's about to clear out, lowkey her whole reason for existing 😭

---

💜 DESCRIPTION 💜

so here's the tea, bestie — this function does exactly one thing:

• Iterate over the list and free each virtual addresses block.

that's it. that's the function. she ate and left no crumbs 🔥

⚠️ okay important caveat, do NOT skip this one: this function should be called only when the va_list lock is taken. like, the name literally has _locked in it, the lock is not optional, it's giving very much "read the room" energy 💀 call it unlocked and that's undefined-behaviour territory, fr fr.
