tracing_alloc_snapshot(9)

💅 tracing_alloc_snapshot — like, the Kernel API Manual (section 9, bestie) ✨

okay so real talk, we're in the kernel API manual, section 9 — yes the big one — and today's main character is tracing_alloc_snapshot. let's get into it 🫶

---

🌸 NAME 🌸

tracing_alloc_snapshot — allocate snapshot buffer. that's it. that's the tweet. 💖

---

✨ SYNOPSIS ✨

int tracing_alloc_snapshot (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments. literally none. she takes nothing, she gives everything. 💅

---

🦋 DESCRIPTION 🦋

okay so here's the vibe check: this only allocates the snapshot buffer if it isn't already allocated — it does not also take a snapshot. so don't come for her expecting a two-for-one, bestie, that's not the assignment. 🙈

she's meant to be used in cases where the snapshot buffer needs to be set up for events that can't sleep but need to be able to trigger a snapshot. lowkey iconic foresight honestly. ⭐

fr fr read that again — allocating ≠ snapshotting. two different girls, two different jobs. 💀
