trace_user_fault_destroy(9)

🦋 trace_user_fault_destroy(9) 🦋

okay so bestie, this is a page from the Kernel API Manual and it's literally the cleanup queen of the trace user fault saga. she's short, she's sweet, she frees stuff. let's get into it 💅

---

✨ NAME ✨

trace_user_fault_destroy — frees up the allocated memory of a trace user buffer 🧚

like, she's the one who shows up at the end of the party with a trash bag. respect her.

---

✨ SYNOPSIS ✨

void trace_user_fault_destroy (struct trace_user_buf_info *tinfo );

no return value, no drama, just vibes and deallocation 🫶

---

✨ ARGUMENTS ✨

• tinfo — the descriptor that needs to be freed up. that's her target, that's the whole assignment. hand her the descriptor and she handles the rest 💖

---

✨ DESCRIPTION ✨

so what she does is: she frees any data that was allocated in the trace info descriptor. that's it, that's the gig. no cap, it's a one-job icon 👑

think of her as the "you're welcome, bye" at the end of trace_user_fault_init. she closes the loop. main character energy but make it memory management 🔥

---

✨ SEE ALSO ✨

okay this list is long and honestly it's giving family reunion 😭 but here's the whole squad, no gatekeeping:

Kernel file ./kernel/trace/trace.c, plus:

trace_array_put(9), tracing_is_enabled(9), tracing_on(9), tracing_snapshot(9), tracing_alloc_snapshot(9), tracer_tracing_disable(9), tracer_tracing_enable(9), tracing_off(9), tracer_tracing_is_on(9), tracing_is_on(9), register_tracer(9), tracing_start(9), tracing_stop(9), trace_buffered_event_enable(9), trace_buffered_event_disable(9), trace_dump_stack(9), ignore_event(9), trace_adjust_address(9), tracing_update_buffers(9), trace_user_fault_init(9), trace_user_fault_get(9), trace_user_fault_put(9), trace_user_fault_read(9), err_pos(9), tracing_log_err(9), trace_array_get_by_name(9), tracing_init_dentry(9)

note that tracing_is_on(9) shows up twice in the list — yep, she's that popular, she got invited twice 💀 not me pointing it out, just saying, it's canon 🌸

---

real talk: if you're holding a struct trace_user_buf_info * that came out of trace_user_fault_init(9), she's the one you call when you're done. don't leave her hanging 🙈

---

and that's the whole page, bestie! 💜 this lil gem lives under ./kernel/trace, dated October 2026, and her full name in the manual is trace_user_fault_destroy(9) — remember her, she cleans up after everyone 🎀✨
