trace_adjust_address(9)

💖 trace_adjust_address — the kernel API glow-up 💖

okay so bestie, welcome to the trace_adjust_address(9) page of the Kernel API Manual 🌸 this one's a lil function with a big job, and we're gonna get into it. no skipping, no skimming, we keep every detail fr fr 💅

---

🎀 NAME 🎀

trace_adjust_address — Adjust prev boot address to current address.

like, it takes an address from a previous boot and makes it make sense in this boot. the way it just... rehomes an address 😭 iconic behaviour honestly.

---

✨ SYNOPSIS ✨

unsigned long trace_adjust_address (struct trace_array *tr , unsigned long addr );

that's the whole signature bestie — returns an unsigned long, takes two args. no cap 🫶

---

💜 ARGUMENTS 💜

• tr — the Persistent ring buffer's trace_array. this is the ring buffer that persists, hence the whole "prev boot" situation. she's the context, she's the vibe 👑
• addr — Address in tr which is adjusted. yeah, that's the one getting the adjustment treatment ✨

lowkey the whole point: that addr belongs to tr, and it's the address being adjusted. don't forget which buffer she came from 🫶

🦋 cute lil sign-off 🦋

this page lives in ./kernel/trace, and it's dated October 2026 — that's the source/version-and-date energy, bestie, we're just saying it cutely instead of in boring footer form ✨ so yeah, ./kernel/trace · October 2026 · trace_adjust_address(9). slay, go adjust some addresses 💅💖
