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.
• 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 scx_sched

Annotated Snippet

#ifndef _KERNEL_SCHED_EXT_ARENA_H
#define _KERNEL_SCHED_EXT_ARENA_H

struct scx_sched;

void scx_arena_pool_destroy(struct scx_sched *sch);
void *scx_arena_alloc(struct scx_sched *sch, size_t size);
void scx_arena_free(struct scx_sched *sch, void *kern_va, size_t size);

Annotation

• Detected declarations: `struct scx_sched`.
• Atlas domain: Core OS / Scheduler, Processes, Timers, Sync, And Syscalls.
• 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.
