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 uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• ../vmlinux.h

Detected Declarations

• struct user_exit_info
• enum uei_sizes

Annotated Snippet

struct user_exit_info {
	int		kind;
	/*
	 * CPU that triggered the exit, or -1 if unset (e.g. running on an
	 * older kernel that does not expose this field).
	 */
	s32		exit_cpu;
	s64		exit_code;
	char		reason[UEI_REASON_LEN];
	char		msg[UEI_MSG_LEN];
};

Annotation

• Immediate include surface: `../vmlinux.h`.
• Detected declarations: `struct user_exit_info`, `enum uei_sizes`.
• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: source 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.
