ssh_ptl_destroy(9)

💖 ssh_ptl_destroy — the kernel API manual, bestie edition ✨

okay so this is the page for ssh_ptl_destroy(9), straight out of the Kernel API Manual. yes we're doing kernel internals today. put your hair up, grab a lil snack, we're cleaning up 🧹💅

🌸 NAME 🌸

ssh_ptl_destroy — deinitialize packet transport layer.

that's it. that's the whole vibe. it's the cleanup girlie. the one who shows up at the end of the party with a trash bag 🎀

---

✨ SYNOPSIS ✨

void ssh_ptl_destroy (struct ssh_ptl *ptl );

no return value, no drama, just vibes and a pointer. 🫶

---

🦋 ARGUMENTS 🦋

• ptl — the packet transport layer to deinitialize. like, the actual one. the one you're done with. hand her over 💜

---

👑 DESCRIPTION 👑

so what does it do? it deinitializes the given packet transport layer and frees resources associated with it. everything it was holding? gone. released. freed. she's decluttering her room and she is NOT asking if it sparks joy 😭

⚠️ okay this is the important part and I need you to actually read it fr fr: if receiver and/or transmitter threads have been started, the layer must first be shut down via ssh_ptl_shutdown before this function can be called. like. do not skip the shutdown step. shut it down first, then destroy. that's the order. that's the rule. bestie I am begging you 🙈

so the correct sequence is: ssh_ptl_shutdown ➡️ ssh_ptl_destroy. iconic order. no notes. ⭐

and that's the page!! 🎀✨

cute lil sign-off moment: this one's from the source path ./drivers/platform/surface/agg... (you know the one, it's the truncated version at the bottom of the page, we love a mysterious ellipsis 💅), dated October 2026, and it lives under ssh_ptl_destroy(9). mwah. bye bestie 🫶🌸
