06 - Disable Kprobes and Jump Labels
Summary
This fragment disables advanced kernel tracing and optimization mechanisms such as kprobes and jump labels. These are mostly useful for debugging or performance tuning during development.
Configuration breakdown
Dynamic instrumentation
CONFIG_KPROBES
- Disables dynamic probes used for kernel debugging.
Jump label optimization
CONFIG_JUMP_LABEL
- Disables static branching optimization using jump labels.
