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

• uapi/linux/signalfd.h
• linux/sched/signal.h

Detected Declarations

• function Copyright
• function signalfd_notify

Annotated Snippet

static inline void signalfd_notify(struct task_struct *tsk, int sig) { }

static inline void signalfd_cleanup(struct sighand_struct *sighand) { }

#endif /* CONFIG_SIGNALFD */

#endif /* _LINUX_SIGNALFD_H */

Annotation

• Immediate include surface: `uapi/linux/signalfd.h`, `linux/sched/signal.h`.
• Detected declarations: `function Copyright`, `function signalfd_notify`.
• 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.
