Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Defines or participates in a user/kernel boundary; inspect argument validation, copy_from_user/copy_to_user, credentials, and dispatch target.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• struct syscall_key
• struct syscall_stats
• enum syscall_aggr_mode

Annotated Snippet

struct syscall_key {
	u64 cgroup;
	int cpu_or_tid;
	int nr;
};

struct syscall_stats {
	u64 total_time;
	u64 squared_sum;
	u64 max_time;
	u64 min_time;
	u32 count;
	u32 error;
};

Annotation

• Detected declarations: `struct syscall_key`, `struct syscall_stats`, `enum syscall_aggr_mode`.
• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: core implementation candidate.

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.
