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

• linux/debug_locks.h
• linux/sched.h
• linux/wait.h
• linux/atomic.h
• linux/jump_label.h

Detected Declarations

• function freezing
• function try_to_freeze
• function cgroup1_freezing
• function frozen
• function freezing
• function __thaw_task
• function freeze_processes
• function freeze_kernel_threads
• function thaw_processes
• function set_freezable

Annotation

• Immediate include surface: `linux/debug_locks.h`, `linux/sched.h`, `linux/wait.h`, `linux/atomic.h`, `linux/jump_label.h`.
• Detected declarations: `function freezing`, `function try_to_freeze`, `function cgroup1_freezing`, `function frozen`, `function freezing`, `function __thaw_task`, `function freeze_processes`, `function freeze_kernel_threads`, `function thaw_processes`, `function set_freezable`.
• Atlas domain: Core OS / Core Kernel Interface.
• 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.
