Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/kexec.h
• linux/purgatory.h

Detected Declarations

• struct kexec_segment
• struct kexec_buf
• function kexec_trylock
• function kexec_unlock
• function kimage_file_post_load_cleanup
• function kho_locate_mem_hole
• function kho_fill_kimage

Annotated Snippet

static inline void kimage_file_post_load_cleanup(struct kimage *image) { }
#endif /* CONFIG_KEXEC_FILE */

struct kexec_buf;

#ifdef CONFIG_KEXEC_HANDOVER
int kho_locate_mem_hole(struct kexec_buf *kbuf,
			int (*func)(struct resource *, void *));
int kho_fill_kimage(struct kimage *image);
#else
static inline int kho_locate_mem_hole(struct kexec_buf *kbuf,
				      int (*func)(struct resource *, void *))
{
	return 1;
}

static inline int kho_fill_kimage(struct kimage *image) { return 0; }

Annotation

• Immediate include surface: `linux/kexec.h`, `linux/purgatory.h`.
• Detected declarations: `struct kexec_segment`, `struct kexec_buf`, `function kexec_trylock`, `function kexec_unlock`, `function kimage_file_post_load_cleanup`, `function kho_locate_mem_hole`, `function kho_fill_kimage`.
• Atlas domain: Core OS / Scheduler, Processes, Timers, Sync, And Syscalls.
• Implementation status: source implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
