# CONFIG_DEBUG_INFO_REDUCED is not set
# LAVD tracks futex to give an additional time slice for futex holder
# (i.e., avoiding lock holder preemption) for better system-wide progress.
# LAVD first tries to use ftrace to trace futex function calls.
# If that is not available, it tries to use a tracepoint.

# Enable extra scheduling features (for a better code coverage while testing
# the schedulers)

Annotation
- Atlas domain: Support Tooling And Documentation / tools.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
