tracer_tracing_enable(9)

💖 tracer_tracing_enable(9) 💖

okay so bestie, this is a page from the Kernel API Manual and honestly it's a short one but it's lowkey iconic — welcome to tracer_tracing_enable ✨

---

🌸 NAME 🌸

tracer_tracing_enable — the counter part of tracer_tracing_disable() 🫶

like, the other half. the remix. the sequel. the "we're so back" of the pair 💅

---

⭐ SYNOPSIS ⭐

void tracer_tracing_enable (struct trace_array *tr );

no cap, that's the whole signature. void in, void out, struct trace_array *tr in the middle, slay 🔥

---

🎀 ARGUMENTS 🎀

• tr — the trace array that had tracer_tracincg_disable called on it 👀

yes bestie, that spelling is exactly how it's written on the page — tracer_tracincg_disable, not tracer_tracing_disable. we are reproducing it character for character because we do not edit the source material 💀

---

🦋 DESCRIPTION 🦋

so here's the vibe check: you call this after tracer_tracing_disable has already been called on tr, at the point where it's safe to re-enable tracing 🌈

that's it. that's the whole thing. it's the "okay we're done being careful, turn the lights back on" function ✨ and the page is very clear about the ordering — after the disable, when it's safe. not before, not whenever, not vibes-based. periodt 👑
