제목	Fast (Trapless) Kernel Probes Everywhere
궁금했던 점	Can Linux Kprobes avoid trap overhead without sacrificing broad kernel-code coverage?
해본 것	The compiler/linker places strategic NOPs that a transparent Kprobe implementation can patch into trapless probes across nearly all code.
당시 조건	Venue: USENIX ATC. Year: 2024. Standard Kprobes trap on every hit; optimized probes are faster but cannot instrument much kernel code. Verification: official_abstract; confidence=high.
실제 결과	workloads=Linux kernel probe sites; baselines=standard Kprobe; prior optimized Kprobe; metrics=probe cost; kernel-code coverage; results=10x probe performance; 96% coverage vs about 80%
왜 그랬는지	Small compile-time layout support removes a runtime observability tax while preserving compatibility.
다음에 기억할 것	Reserve cheap patch points during build time for production-safe dynamic instrumentation.
언제 맞는지	Linux tracing, observability, and security instrumentation. Limits: Needs toolchain/kernel-layout changes; some code and architectures remain unsupported.

Verification: official_abstract; confidence=high. Canonical title: Fast (Trapless) Kernel Probes Everywhere Question: Can Linux Kprobes avoid trap overhead without sacrificing broad kernel-code coverage? Context: Standard Kprobes trap on every hit; optimized probes are faster but cannot instrument much kernel code. Method: The compiler/linker places strategic NOPs that a transparent Kprobe implementation can patch into trapless probes across nearly all code. Evaluation: workloads=Linux kernel probe sites; baselines=standard Kprobe; prior optimized Kprobe; metrics=probe cost; kernel-code coverage; results=10x probe performance; 96% coverage vs about 80% Interpretation: Small compile-time layout support removes a runtime observability tax while preserving compatibility. Reusable lesson: Reserve cheap patch points during build time for production-safe dynamic instrumentation. Applicability: Linux tracing, observability, and security instrumentation. Limits: Needs toolchain/kernel-layout changes; some code and architectures remain unsupported.
